Hot Bar Soldering Machine – A Small Number of Ideas About Deciding on a Hot Bar Soldering Machine.

We would like to provide you with the right technology for that efficient soldering procedure for our connection technology. Therefore we certainly have developed and implemented a very interesting solution. The New Bar Soldering process connects different connection parts together. Due to the fact that the contact pads are often soldered into a PCB it is essential that the materials used provide a slightly different alloy, where reliable solder points can be produced. Prior to the soldering process one of many two solder points is coated with flux and so the connector part is pressed onto this time through the still cold thermode. Subsequently a concise heating from the hot bar soldering machine is conducted until the melting temperature is reached. The device is cooled off really quick right after the soldering has gotten place. Air is virtually always used for the cooling.


Although Hot Bar Soldering is really a single solder process multiple solder connections are almost always produced. One more great advantage will be the mechanical fixation of your solderable part through the thermode ahead of the soldering process starts. For that reason both parts can perfectly be employed towards the appropriate position.

Previous technique

Currents between 150 and 300 Ampere are employed to heat the thermode. In classical systems the existing is generated by way of a transformer. Due to thick supply cables (thumb’s width) leading the current to the thermode these systems are nearly immobilized. They merely move several millimeters toward the stroke which is sufficient to result in cable breaks – especially at the thermode connection – in the 24/7 operation.

Our technique

We use currents approximately 300 Ampere within the thermode, but in our approach the thermode is placed directly behind the power electronics which converts the input current of circa 15 Ampere (input voltage 24V) up to 300 Ampere. The 24 Volt supply line is thin as compared to the supply lines of conventional systems. Additionally the whole system is packed within an aesthetic designer housing.


During the soldering of Auto Soldering Machine behave as down the road application: They dissipate heat well which makes it difficult to connect a part using these PCBs by soldering. The best solution for this problem is a Hot Bar soldering system simply because it applies enough energy to the solder points in order to create a reliable connection in just a small amount of time. Interesting applications

We provide the suitable connecting elements to maintain sufficient high current flow.

Practical Example:

One application is the creation of a daytime running light with high power LEDs mounted onto an Aluminum core PCB and linked to one other. In this case the bond technology consists of THT-jumpers with Hot Bar Soldering pads. The soldering was done by Hot Bar Soldering process:


We present the center in our system, the new Bar Soldering Generator BLG-300. Its design is unique and is particularly only exceeded by its function.

Setup in the thermode

Usually thermodes are constructed with stainless, but also other materials, e.g. Wolfram is achievable We deliver an extensive selection of different widths and we often adapt the thermodes individually for the customers soldering requirements. Because of a special thermode profile we achieve an exceptionally homogeneous heating. Integrated within the thermode there exists a temperature sensor positioned in a way to generate as close as you can measurement results. As a result of complete pluggable connections the change from the thermode is indeed simple that you desire about 1 minute. For series production we recommend buying two Hot Bar Soldering Generators to change the thermode without time-related stress or production interruption.

Working cycle

Due to our special generator technique ultimately causing a better power of your Soldering Bar in the thermode and also the compatible control electronics this site offers a rapid, high-performance system. Subsequently we chart a working cycle diagram since it is used to solder flex strips to some PCB. Depending on the application the cycle times can differ soon enough. By performing in-house experiments and continuous parameter adjustment the ideal cycle times are achieved. Oftentimes our systems are employed in three eight-hour shifts where a split second is essential. Thereby, you should pick the cool down time – the time for cooling the solder bar before it is actually lifted up from your soldering point.

Tabletop system BLS-50

Our Hot Bar Soldering system BLS-50 is a complete system for direct utilization in the ongoing production. The New Bar Soldering station is based on a universal mounting in the base plate where various equipment does apply. We can easily also construct and provide the perfect mounting setup. In its simplest form you send us the various components which have to be soldered and we construct the compatible mounting plate for you personally.

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

Upon request the new Bar Soldering station BLS-50 (model BLS-50-D)is offered which allows the strain to get monitored electrically. In this instance, a precise control unit for 15dexopky together with the prescribed target pressure values is provided. This special function is important for all processes where materials are soldered to very sensitive substrates in addition to monitoring and documenting all production parameters permanently. The control electronics that happen to be included enables the setting of your following parameters:

Production line

Within our affiliated company, NE-Sensoric GmbH & Co. KG, we build production lines matching perfectly to the Hot Bar Soldering system. Again, the target is obviously on a universal possible application. The modular construction shortens the development and delivery time. By the use of industrial robots the new Bar Soldering system has the capacity to solve just about any soldering task. Soldering in angular positions, offset rows along with different positions are no issue for your system. In order to change the LED Soldering Machine our recommendation is that you replace the entire solder head since time required is less than a minute. Such a system allows the customization to each and every new production situation in your company.
