LED HotBar Machine – A Lot of Different Suggestions About Selecting a LED HotBar Machine.

We want to present you with a suitable technology for your efficient soldering process of our connection technology. Therefore we have now developed and implemented an incredibly interesting solution. The Recent Bar Soldering process connects different connection parts collectively. Because of the fact that the contact pads are usually soldered to a PCB it is important that materials used give you a slightly different alloy, by which reliable solder points can be produced. Just before the soldering process one of several two solder points is coated with flux and therefore the connector part is pressed onto this point through the still cold thermode. Subsequently a quick heating of the Automatic soldering machine is carried out till the melting temperature is reached. The system is cooled off really quick once the soldering has taken place. Air is virtually always useful for the cooling.


Although Hot Bar Soldering is actually a single solder process multiple solder connections are almost always produced. Yet another excellent advantage will be the mechanical fixation of the solderable part from the thermode just before the soldering process starts. As a result both parts can perfectly be applied on the appropriate position.

Previous technique

Currents between 150 and 300 Ampere are used to heat the thermode. In classical systems the actual is generated by way of a transformer. On account of thick supply cables (thumb’s width) leading the current towards the thermode these systems are nearly immobilized. They merely move a number of millimeters toward the stroke that is sufficient to cause cable breaks – especially with the thermode connection – in the 24/7 operation.

Our technique

We also use currents up to 300 Ampere within the thermode, nevertheless in our approach the thermode is put directly behind the energy electronics which converts the input current of circa 15 Ampere (input voltage 24V) approximately 300 Ampere. The 24 Volt supply lines are thin in comparison to the supply lines of conventional systems. And also the whole technique is packed in a aesthetic designer housing.


Through the soldering of Auto Soldering Machine behave as later on application: They dissipate heat well rendering it difficult to connect a part with one of these PCBs by soldering. The ideal solution for this issue is a Hot Bar soldering system simply because it applies enough energy towards the solder points as a way to create a reliable connection inside a short period of time. Interesting applications

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

Practical Example:

One application is the creation of a daytime running light with good power LEDs mounted onto an Aluminum core PCB and attached to one other. In cases like this the connection technology contains THT-jumpers with Hot Bar Soldering pads. The soldering was done by Hot Bar Soldering process:


We present the center of the system, the recent Bar Soldering Generator BLG-300. Its design is exclusive and is particularly only exceeded by its function.

Setup from the thermode

Usually thermodes are constructed with stainless-steel, but additionally many other materials, e.g. Wolfram is achievable We deliver a wide range of different widths and we often adapt the thermodes individually to the customers soldering requirements. Caused by a special thermode profile we achieve an exceptionally homogeneous heating. Integrated within the thermode there is a temperature sensor positioned in ways to produce as close as you possibly can measurement results. Due to complete pluggable connections the alteration of your thermode is really simple that you desire about 1 minute. For series production we recommend buying two Hot Bar Soldering Generators to modify the thermode without time-related stress or production interruption.

Working cycle

Because of our special generator technique resulting in a higher power of the Soldering Bar with the thermode and the compatible control electronics this site offers a fast, high-performance system. Subsequently we chart a working cycle diagram because it is employed to solder flex strips to some PCB. Based on the application the cycle times may differ over time. By performing in house experiments and continuous parameter adjustment the perfect cycle times are achieved. In many cases our systems function in three eight-hour shifts when a split second is vital. Thereby, it is very important choose the cool down time – time for cooling the solder bar before it can be 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 dependant on a universal mounting in the base plate where various equipment does apply. We can easily also construct and create the suitable mounting setup. In their simplest form you send us the various components which are to be soldered therefore we construct the compatible mounting plate for you.

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

Upon request the Bar Soldering station BLS-50 (model BLS-50-D)is available that allows the strain being monitored electrically. In cases like this, a precise control unit for 15dexopky together with the prescribed target pressure values is supplied. This special function is essential for many 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 from the following parameters:

Production line

In our affiliated company, NE-Sensoric GmbH & Co. KG, we build production lines matching perfectly to the Hot Bar Soldering system. Again, the focus is usually over a universal possible application. The modular construction shortens the development and delivery time. By means of industrial robots the Hot Bar Soldering system can solve just about any soldering task. Soldering in angular positions, offset rows as well as different positions are no worries for the system. In order to change the LED HotBar Machine our recommendation is that you replace the total solder head since time required is less than a minute. Such a system allows the customization to every single new production situation inside your company.
