User guide

In the journey of Junior IOT and Junior IOT Onderwijs BV we have compared and used many different soldering irons. We learned which qualities are important in the classroom. You can read more about our search here: https://junioriot.nl/product/soldeerwerkplek/

The search resulted in finding our best choice: The soldering equipment around the Junior IOT ST12A Mini Soldering Regulator. The safe and user-friendly T12 DC soldering controller with LED display and external power supply gives our users the best experience – compact, safe and robust for a school environment, precise and simple to use for our audience, while still appealing to the desires of a professional hobbyist.

Having found our perfect piece of equipment, we have decided in 2022 to ask the manufacturer to add our name to the front panel: The Junior IOT ST12A Mini Soldering Regulator.

Brief description

In our soldering setup, the ST12A regulator unit is recognized as the black rectangle box shaped component that connects to the power supply to the soldering handset. Our model features a LCD temperature display, a knob to be rotated and pushed for temperature adjustment, a connection point for the external 19V DC power and a connection point for the soldering handset. The mini device is to be powered by any external laptop power supply of 19 Volt DC.

The Junior IOT ST12A Mini Soldering Regulator is specifically only the rectangular box. The additional items (power supply, handle, T12 tip) can be of various makes and models. The word ‘regulator’ indicates the need to complete your setup with your preference of these other items.

Additional components to complete your soldering setup

The regulator is the brain component in your soldering setup. The regulator reads the actual temperature from the soldering tip and then enables the DC power that is to be sent to the T12 soldering tips for heating. You will need to source these additional components to complete the Junior IOT ST12A Mini Soldering Regulator. To be added:

• T12 handle. Please purchase a matching T12 handle. Select a fully wired 5 pin version to allow the wake-up function, and with silicon wiring for additional safety.
• T12 soldering tips. We suggest you purchase one of these shapes: T12-I, T12-BL, T12-IL and T12-ILS. This is where the solder meets the metal.
• DC Power Supply. As this is the one item that connects to the mains power, please ensure your 19V DC power supply is correctly CE certified.

Additionally, for your comfort:

• Silicon work mat.
• Heat-proof soldering stand, mini version.
• Heat-proof soldering sponge to clean the soldering tip.

These components are typically manufactured separate from the regulator. You are free to purchase the versions that you find most comfortable for your usage. We have made our own selection available to complete your own soldering workspace to contain all these components.

Why this page?

We learned our lessons quickly in 2022 when EU import professionals refused our shipment in 2022. In that process we learned which details are needed on the product, and which online documentation is required. This current page is created to comply with the requirements of our position as the official importer of the product.

Independent from our initial choice to use the product mainly inside our own organization, we need to demonstrate CE compliance to support successfully shipments of the product to our own address. This page provides you as a customer with the product information to safely use our product, and also presents any EU official with the official information and documentation relevant to allowing our product onto the EU market.

Commissioning the factory to add the Junior IOT label

We have instructed the factory to add our Junior IOT brand name to the controller unit to confirm our recognition of this product. As part of the import process, we found that it is required to officially confirm our authority to commission our brand name. We will do so in the next few paragraphs.

Confirm our authority for the Junior IOT brand name

EU regulations clarify that imported goods should carry the correct brand name to prevent EU customers from counterfeit goods. We have indeed received this explicit request from import officials, asking to provide proof of authorization to the factory to use the Junior IOT label. In this section we demonstrate proof for our history and for our ownership of the brand name.

The Junior IOT name came to life in 2016, when we started our first project in december 2016, preparing for our 2017 Balloons Up challenge. The Junior IOT name was created for our projects. Project documentation from this period is available at: http://junioriotchallenge.nl/

In 2019 we have registered a first part of our organization as an official foundation (dutch: Stichting). The initial scope of the foundation is to manage the local Junior IOT makerspace in Alkmaar. Details and founding documents are available at: https://junioriot.nl/stichting/

In 2023 we have registered the second part of our operation as the company Junior IOT Onderwijs BV. This now serves as the main entity where most activities reside. Details and documents are available at: https://junioriot.nl/junior-iot-onderwijs-bv/

Both the Stichting Junior IOT and Junior IOT Onderwijs BV are authorized to use the ‘Junior IOT’ brandname. All addresses of both organizations as mentioned on the JuniorIOT.nl website are valid shipping targets to allow shipment of items carrying the ‘Junior IOT’ logo into the EU. To help in authorizing the shipments, this page certifies the following addresses in Alkmaar.

• Cabeljaustraat 9, 1815GD Alkmaar. Certification in official documents: the registration at the Chamber of Commerce (in dutch: Kamer van Koophandel or KvK) confirms Junior IOT (Stichting Junior IOT) as our brand name and confirms this is connected to the postal address Cabeljaustraat 9, 1815GD Alkmaar. The official extract is called ‘Uittreksel Kamer van Koophandel’ and can be found here:   https://junioriot.nl/app/uploads/2000/12/uittreksel_handelsregister_75357984.pdf
• Hornwaard 34, 1824 SE Alkmaar. Certification in official documents: the registration at the Chamber of Commerce (in dutch: Kamer van Koophandel or KvK) confirms Junior IOT (Junior IOT Onderwijs BV) as our brand name and confirms how this is connected to the postal address Hornwaard 34, 1824 SE Alkmaar. The official extract is called ‘Uittreksel Kamer van Koophandel’ and can be found here: KVK_Recherche_89566866_15_03_2023_16-47-09
• Bannewaard 164, 1824 EG Alkmaar. Our internet page confirms this address as the shipping address for both Stichting Junior IOT and Junior IOT Onderwijs BV: https://junioriot.nl/junior-iot-onderwijs-bv/

Furthermore, if more confirmation is needed, the Junior IOT domain name is registered at amazon, and replicated for loadbalancing at cloudflare, including the dutch and international variations. For your confirmation, we have published our authenticity details in a TXT record as a public viewable proof of authority. Please use your preferred online viewer e.g.: https://mxtoolbox.com/SuperTool.aspx?action=txt%3ajunioriot.nl&run=toolpage or https://dnslookup.online/txt.html

This will allow you to review our DNS key in our domain registration, to confirm our authority and ownership of the brandname Junior IOT, connecting the details to our address. The public information should read similar to:

“Cloudflare DNS. Stichting Junior IOT, in Alkmaar and Junior IOT Onderwijs BV, Hornwaard 34 in Alkmaar are the owners of the brand name Junior IOT. KvK registration numbers 75357984 and 89566866 are registered in the Netherlands on july 11, 2019 and march 15, 2023.”

The above statements confirm our ownership of the brandname ‘Junior IOT’ and our authority to commission the use of the name Junior IOT. For further questions, please contact us at [email protected].

Valid shipments – Commisioning the manufacturer to import our products for the Junior IOT label

In 2022 we commissioned the manufacturer to make our first branded version of the soldering regulator component. Please be aware that now the brand name, type number and product link are printed on the product to satisfy EU market needs.

With our ownership of the ‘Junior IOT’ brand name confirmed, we are authorized to commission the ‘Junior IOT’ branded products to officially display our connection with, our approval of, and our EU support for these products.

For import officials to be able confirm the shipment as authorized to use ‘Junior IOT’ brand label we provide the following authorization information:

Manufacturer product CE certification for the EU market

For electronic devices available on the EU market, the relevant CE certifications and approvals need to be readily available. This section presents the official certifications and documents as supplied by the manufacturer.

LVD, Low Voltage Directive. As the working voltage of the device is 19 Volt DC, then working voltage is lower than the power levels regulated in the Low Power Directive, and as such the Low Power Directive is not applicable. For this we review the document https://www.zvei.org/fileadmin/user_upload/Presse_und_Medien/Publikationen/2013/maerz/Role_of_CE_marking_in_the_placing_on_the_market_of_electronic_components/Position-CE-Components-2013-EN.pdf

Low Voltage Directive 2006/95/EC The Low Voltage Directive (LVD) governs the safety of ‘electrical equipment’ with a voltage between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current, according to its Article 1. The operational voltage of many electronic components lies outside this range. Therefore, such components do not fall under the scope of the Low Voltage Directive.

Nevertheless the factory has provided the EMC and LVD certificates for the product, which confirm the CE certification for the product and confirms the CE logo can be applied to demonstrate compliance.

EMC, Electro Magnetic Certification. The product has been tested to comply to the EMC directive. The certificate is available as PDF (document: 812A-CE-EMC) and is available on the BST website (link: http://www.bst-lab.com/index.php?g=Contents&m=Index&a=search&q=BSTXD220421291601EC).

User guide

We need to tell the users that many variations of this product could have the same or similar internal controller specifications. We limit this description to only the version as imported by Junior IOT.

Description. The Junior IOT ST12A Mini Soldering Regulator is the basis for your soldering setup. Combined with a handset, T12 tip, power supply of your choice, this combines into a 72W PID Soldering Iron which is compact, safe, simple and comfortable to work with.

The Junior IOT ST12A Mini Soldering Regulator is recognized as the compact black box, featuring a LCD display, a knob to adjust temperature, a connection point for the T12 handle and a connection point for the standard power supply.

Please be aware that in other versions exist. Some versions may have the power supply embedded with the regulator display in the same box, where you may need to check the internals for safety implications. Also, any version that features a detailed OLED display is not included in our information as it has a very different controller.

Soldering temperature. The Junior IOT ST12A Mini Soldering Regulator displays the actual temperature trough a 3 digit LCD display. You can adjust the temperature 200-480 degrees Celsius by turning the knob. Recommended temperatures:

• 280-300 degrees Celsius – soldering SMD and fine work using leaded soldering tin
• 350 degrees Celsius – for beginners and for standard components using leaded soldering tin
• 350 degrees Celsius – for components using unleaded soldering tin (ensure that the tip is clean)

Be aware that above 360 degrees Celsius, the soldering results will appear erratic due to overheating of the flux inside the soldering material. Also at higher temperatures, for example above 380 degrees Celsius, the tip will deteriorate more quickly.

Additional settings. We suggest to leave the regulator unit in its default settings. By pressing the knob for a brief period, you enter the settings menu. Available settings:

• P00-P03 –  tip type and calibration, available for some types
  • P01 – PID gain 200-350 times (default 270)
  • P02 – Opamp bias voltage 0-250mV (default 100) to help calibrate if tip temperature was measured externally
  • P03 – Increase the temperature, 30-50 deg C
• P04 – Temp adjustment steps. 0 no adjustment or locked, 1, 2, 5 degrees, 10 degrees
• P05 – Auto Sleep timer, 0 never, or 1-60 minutes
• P06 – Auto Shut down timer. 0 never, or 1-180 minutes
• P07 – Temperature correction. 0-20 deg C
• P08 – Wake Up. 0 Shake and Knob press/rotate, 1 Knob press/rotate only
• P09 – Temp Boost temperature in degrees, boost is activated by clicking the Knok
• P10 – Temp Boost duration, 10-250 Seconds
• P11 – Automatic save time of parameters
• P12 – Sound. 0 On, 1 Off (or function cancellation)

Preparing the soldering equipment.

To connect the T12 handle to the main unit, please ensure correct orientation of the lock and pins. Insert the connector and lock it in place with the screw sleeve.

With the device turned on, insert the tip into the handle, and confirm that the controller displays an increasing temperature. Please be aware the tip will get hot. If the controller does not detect the tip, you may need to push or twist the tip further into the handle. If a lock ring is available on the handle, lock the tip in place with the lock ring. With some fancy handles (metal type) an error may be displayed when the internal connector to the tip may have shifted; just push the black cable back into the handle to regain proper connection.

Once the tip is inserted for the first time, you may notice an erratic/jumpy display of temperature. The internal factory glue inside the tip may need to be cured for a few minutes, after which the display will be more stable. If, after many hours of use, such erratic/jumpy display of temperature returns, this may be a signal that you need to renew the tip.

Usage.

Heat-up time typically is 5-10 seconds.

When powering on the device, a memory function will keep the last used temperature.

After a period of non-use, the device enters a safety mode where the temperature is 200 degrees Celcius. Shake the handle or push the knob to wake up the device.

After a prolonged period of non-use the device will display ‘OFF’ and the temperature drops further. Push the knob to wake up the device.

Boost function. Pressing the knob raises the temperature for a brief moment to the set boost temperature.

Safety. Due to having an external DC power unit, the device is safe and in agreement with all regulations. Your DC power unit needs to be correctly CE certified to provide the desired safety. We strongly suggest to use a grounded 19V DC power adapter, although this is not required by certification authorities. A grounded DC adapter will ensure that the soldering tip is connected with the ground lead – through the grounded minus lead in the 19V DC power connector.

Conclusion. Our soldering setup is comfortable, easy and safe and easy to use. This makes it a perfect fit for our school and workshop environment. We have added the Junior IOT name to confirm our approval and support while ensuring compliance with EU regulations.
