Hot Bar Soldering Machine – A Variety of Ideas About Purchasing a Hot Bar Soldering Machine.

We wish to supply you with a suitable technology for that efficient soldering procedure for our connection technology. Therefore we have developed and implemented an extremely interesting solution. The New Bar Soldering process connects different connection parts with each other. Mainly because the contact pads are frequently soldered to a PCB it is crucial that the materials used provide a slightly different alloy, in which reliable solder points can be produced. Just before 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 short heating from the Automatic soldering machine is carried out until the melting temperature is reached. The device is cooled down extremely fast following the soldering has taken place. Air is nearly always employed for the cooling.


Although Hot Bar Soldering can be a single solder process multiple solder connections are typically produced. Another excellent advantage is definitely the mechanical fixation of the solderable part with the thermode prior to the soldering process starts. Consequently 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 actual is generated from a transformer. On account of thick supply cables (thumb’s width) leading the present on the thermode these systems are nearly immobilized. They simply move several millimeters in the direction of the stroke which happens to be sufficient to cause cable breaks – especially on the thermode connection – inside a 24/7 operation.

Our technique

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


Through the soldering of Auto Soldering Machine behave as down the road application: They dissipate heat very well rendering it difficult to connect a part by using these PCBs by soldering. The best solution with this concern is a Hot Bar soldering system because it applies enough energy for the solder points to be able to develop a reliable connection inside a small amount of time. Interesting applications

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

Practical Example:

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


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

Setup of the thermode

Normally the thermodes are made of stainless steel, and also many other materials, e.g. Wolfram can be done We deliver a broad range of different widths and we often adapt the thermodes individually on the customers soldering requirements. As a result of special thermode profile we achieve a very homogeneous heating. Integrated in the thermode there exists a temperature sensor positioned in such a way to generate as near as you possibly can measurement results. Due to the complete pluggable connections the modification in the thermode is really simple you need about 1 minute. For series production we recommend buying two Hot Bar Soldering Generators to modify the thermode without time-related stress as well as production interruption.

Working cycle

Because of our special generator technique resulting in a higher power from the Soldering Bar in the thermode and also the compatible control electronics we offer a speedy, high-performance system. Subsequently we chart a working cycle diagram because it is used to solder flex strips to some PCB. Dependant upon the application the cycle times can vary over time. By performing in house experiments and continuous parameter adjustment the ideal cycle times are achieved. Oftentimes our systems operate in three eight-hour shifts where a split second is very important. Thereby, it is very important choose the cool off 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 actually a complete system for direct use in the ongoing production. The New Bar Soldering station is based on a universal mounting within the base plate where various equipment can be applied. We could also construct and create the ideal mounting setup. Within its simplest form you send us the parts which need to be soldered and that we construct the compatible mounting plate to suit your needs.

Together with the included control electronics all required parameters might 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 supply and compressed air (6-8 bar) is needed. The device is made up of the tabletop along with the associated power supply:

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

Production line

Inside our affiliated company, NE-Sensoric GmbH & Co. KG, we build production lines matching perfectly to our own Hot Bar Soldering system. Again, the focus is obviously on the universal possible application. The modular construction shortens the development and delivery time. Using industrial robots the Hot Bar Soldering system has the capacity to solve just about any soldering task. Soldering in angular positions, offset rows and also different positions are no issue for our own system. In order to affect 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 new production situation within your company.
