LED Soldering Machine – Assorted Ideas on Getting a LED Soldering Machine.

We wish to present you with a suitable technology to the efficient soldering procedure for our connection technology. Therefore we certainly have developed and implemented a very interesting solution. The Recent Bar Soldering process connects different connection parts together. Due to the fact the contact pads are frequently soldered into a PCB it is important that the type of material used offer a slightly different alloy, in which reliable solder points can be created. Ahead of the soldering process one of several two solder points is coated with flux and then the connector part is pressed onto this aspect from the still cold thermode. Subsequently a quick heating in the hot bar soldering machine is performed up until the melting temperature is reached. The device is cooled down very fast following the soldering is taking place. Air is nearly always utilized for the cooling.


Although Hot Bar Soldering is a single solder process multiple solder connections are usually produced. Yet another excellent advantage is definitely the mechanical fixation in the solderable part by the thermode prior to the soldering process starts. For that reason both parts can perfectly be employed to 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 existing on the thermode these systems are nearly immobilized. They just move a number of millimeters toward the stroke which is sufficient to cause cable breaks – especially in the thermode connection – inside a 24/7 operation.

Our technique

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


In the soldering of Auto Soldering Machine behave as in the foreseeable future application: They dissipate heat well making it tough to connect a part with one of these PCBs by soldering. The best solution for this problem is a Hot Bar soldering system simply because it applies enough energy on the solder points as a way to develop a reliable connection in a limited time. Interesting applications

We offer the suitable connecting elements to preserve 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 another. In this case the bond technology consists of THT-jumpers with Hot Bar Soldering pads. The soldering was completed by Hot Bar Soldering process:


We present the heart of our own system, the Hot Bar Soldering Generator BLG-300. Its design is unique and is particularly only exceeded by its function.

Setup of your thermode

Usually the thermodes are created from stainless, but in addition many other materials, e.g. Wolfram is achievable We deliver a large variety of different widths so we often adapt the thermodes individually on the customers soldering requirements. As a result of special thermode profile we achieve an extremely homogeneous heating. Integrated inside the thermode there exists a temperature sensor positioned in a way to generate as close as is possible measurement results. As a result of complete pluggable connections the alteration from the thermode is indeed simple that you require about one minute. For series production we recommend buying two Hot Bar Soldering Generators to modify the thermode without time-related stress and even production interruption.

Working cycle

Due to our special generator technique creating a better power of the Soldering Bar on the thermode along with the compatible control electronics this site offers a quick, high-performance system. Subsequently we chart a working cycle diagram since it is utilized to solder flex strips to your PCB. Dependant upon the application the cycle times can vary with time. By performing in-house experiments and continuous parameter adjustment the ideal cycle times are achieved. On many occasions our systems are employed in three eight-hour shifts wherein a split second is very important. Thereby, you should select the cool down time – enough time for cooling the solder bar before it really is lifted up in the 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 Bar Soldering station will depend on a universal mounting from the base plate where various equipment does apply. We could also construct and provide the perfect mounting setup. In the simplest form you send us the various components which should be soldered and that we construct the compatible mounting plate for you personally.

With all the included control electronics all required parameters could be set. The apparatus is controlled with a two-button operation along with 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 necessary. The system contains the tabletop as well as the associated power supply:

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

Production line

Inside our affiliated company, NE-Sensoric GmbH & Co. KG, we build production lines matching perfectly to our Hot Bar Soldering system. Again, the target is definitely on the universal possible application. The modular construction shortens the development and delivery time. By means of industrial robots the Hot Bar Soldering system can solve virtually every soldering task. Soldering in angular positions, offset rows and also different positions are no problem for your system. If you wish to alter the LED Soldering Machine we recommend that you replace the total solder head since time required is under a minute. This type of system allows the customization to each new production situation in your company.
