Automatic Soldering Machine – A Large Number of Ideas About Selecting a Automatic Soldering Machine.

We wish to provide you with an appropriate technology for the efficient soldering process of our connection technology. Therefore we have developed and implemented a really interesting solution. The Bar Soldering process connects different connection parts collectively. Simply because that this contact pads are frequently soldered into a PCB it is essential that the materials used provide a slightly different alloy, through which reliable solder points can be accomplished. Just before the soldering process one of many two solder points is coated with flux and then the connector part is pressed onto this time by the still cold thermode. Subsequently a concise heating in the Automatic soldering machine is performed until the melting temperature is reached. The machine is cooled off very fast right after the soldering has brought place. Air is nearly always used for the cooling.


Although Hot Bar Soldering can be a single solder process multiple solder connections are more often than not produced. Another great advantage is the mechanical fixation of your solderable part with the thermode ahead of the soldering process starts. Because of this both parts can perfectly be used for the appropriate position.

Previous technique

Currents between 150 and 300 Ampere are used to heat the thermode. In classical systems the existing is generated by a transformer. Due to thick supply cables (thumb’s width) leading the present on the thermode these systems are nearly immobilized. They merely move several millimeters in the direction of the stroke which can be sufficient to cause cable breaks – especially with the thermode connection – in the 24/7 operation.

Our technique

We also use currents around 300 Ampere inside the thermode, however in our approach the thermode is positioned directly behind the power electronics which converts the input current of circa 15 Ampere (input voltage 24V) around 300 Ampere. The 24 Volt supply lines are thin as compared to the supply lines of conventional systems. Additionally the whole product is packed in an aesthetic designer housing.


During the soldering of Robotic Soldering Machine behave as down the road application: They dissipate heat adequately making it hard to connect a part using these PCBs by soldering. The optimal solution just for this issue is a Hot Bar soldering system simply because it applies enough energy to the solder points to be able to create a reliable connection in a limited time. Interesting applications

We also offer the suitable connecting elements to keep up sufficient high current flow.

Practical Example:

One application is the production of a daytime running light with higher power LEDs mounted onto an Aluminum core PCB and linked to the other person. In such a case the connection technology contains THT-jumpers with Hot Bar Soldering pads. The soldering was completed by Hot Bar Soldering process:


We present the center in our system, the recent Bar Soldering Generator BLG-300. Its design is different in fact it is only exceeded by its function.

Setup of the thermode

Usually the thermodes are made from stainless, but additionally many other materials, e.g. Wolfram can be done We deliver a broad selection of different widths and that we often adapt the thermodes individually towards the customers soldering requirements. As a result of special thermode profile we achieve an extremely homogeneous heating. Integrated from the thermode there exists a temperature sensor positioned in ways to make as near as is possible measurement results. Because of the complete pluggable connections the modification of your thermode is so simple that you require about one minute. For series production we recommend buying two Hot Bar Soldering Generators to improve the thermode without time-related stress as well as production interruption.

Working cycle

Due to our special generator technique creating a better power of your Soldering Bar with the thermode along with the compatible control electronics we offer a speedy, high-performance system. Subsequently we chart a working cycle diagram because it is utilized to solder flex strips to a PCB. Dependant upon the application the cycle times may differ with time. By performing on-site experiments and continuous parameter adjustment the perfect cycle times are achieved. On many occasions our systems function in three eight-hour shifts when a split second is crucial. Thereby, you should pick the cool down time – the time for cooling the solder bar before it really is lifted up from your soldering point.

Tabletop system BLS-50

Our Hot Bar Soldering system BLS-50 is really a complete system for direct utilize in the ongoing production. The Recent Bar Soldering station is based on a universal mounting within the base plate where various equipment can be applied. We can also construct and produce the suitable mounting setup. Within its simplest form you send us the parts which should be soldered so we construct the compatible mounting plate for you personally.

Together with the included control electronics all required parameters may be set. The apparatus is controlled with a two-button operation as well as the whole device corresponds to the current CE safety standard. To implement the Soldering system a 380 Volt (16A) power source and compressed air (6-8 bar) is essential. The device contains the tabletop and also the associated power supply:

Upon request the Hot Bar Soldering station BLS-50 (model BLS-50-D)is available allowing the pressure to get monitored electrically. In this case, a precise control unit for 15dexopky with all the prescribed target pressure values is provided. This special function is vital for those processes where materials are soldered to very sensitive substrates and also monitoring and documenting all production parameters permanently. The control electronics that happen to be included enables the setting in the following parameters:

Production line

In your affiliated company, NE-Sensoric GmbH & Co. KG, we build production lines matching perfectly to your Hot Bar Soldering system. Again, the main objective is always on the universal possible application. The modular construction shortens the production and delivery time. Through industrial robots the Bar Soldering system will be able to solve just about any soldering task. Soldering in angular positions, offset rows along with different positions are no problem for the system. If you wish to alter the LED HotBar Machine our recommendation is that you replace the complete solder head since time required is under a minute. Such a system allows the customization to each and every new production situation inside your company.
