We would like to give you a good technology for your efficient soldering procedure of our connection technology. Therefore we have developed and implemented an extremely interesting solution. The Hot Bar Soldering process connects different connection parts together. Mainly because how the contact pads are often soldered into a PCB it is vital that the type of material used give a slightly different alloy, in which reliable solder points can be produced. Just before the soldering process among the two solder points is coated with flux and so the connector part is pressed onto this aspect with the still cold thermode. Subsequently a short heating of your hot bar soldering machine is carried out before the melting temperature is reached. The machine is cooled off fast once the soldering has taken place. Air is nearly always useful for the cooling.
Although Hot Bar Soldering is actually a single solder process multiple solder connections are almost always produced. Another great advantage is the mechanical fixation of the solderable part through the thermode before the soldering process starts. As a result both parts can perfectly be employed on the appropriate position.
Currents between 150 and 300 Ampere are used to heat the thermode. In classical systems the actual is generated from a transformer. Due to thick supply cables (thumb’s width) leading the current for the thermode these systems are nearly immobilized. They merely move several millimeters toward the stroke that is sufficient to cause cable breaks – especially in the thermode connection – in the 24/7 operation.
We use currents as much as 300 Ampere from the thermode, nevertheless 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 in a aesthetic designer housing.
Through the soldering of Robotic Soldering Machine behave as down the road application: They dissipate heat well rendering it tough to connect a part with one of these PCBs by soldering. The optimal solution with this concern is a Hot Bar soldering system simply because it applies enough energy towards the solder points to be able to create a reliable connection in just a small amount of time. Interesting applications
We supply the suitable connecting elements to keep sufficient high current flow.
One application is producing a daytime running light with good power LEDs mounted onto an Aluminum core PCB and associated with one other. In this instance the connection technology is made up of THT-jumpers with Hot Bar Soldering pads. The soldering was completed by Hot Bar Soldering process:
We present the heart in our system, the recent Bar Soldering Generator BLG-300. Its design is unique which is only exceeded by its function.
Setup in the thermode
Usually thermodes are made from stainless-steel, but additionally other materials, e.g. Wolfram is possible We deliver a wide variety of different widths therefore we often adapt the thermodes individually to the customers soldering requirements. Due to a special thermode profile we achieve an incredibly homogeneous heating. Integrated from the thermode there is a temperature sensor positioned in ways to make as near as is possible measurement results. Due to complete pluggable connections the modification of the thermode is so simple you need about 1 minute. For series production we recommend buying two Hot Bar Soldering Generators to improve the thermode without time-related stress or production interruption.
As a result of our special generator technique ultimately causing a better power of your Soldering Bar at the thermode and also the compatible control electronics we provide a quick, high-performance system. Subsequently we chart a working cycle diagram as it is utilized to solder flex strips to your PCB. Dependant upon the application the cycle times may vary over time. By performing on-site experiments and continuous parameter adjustment the optimal cycle times are achieved. On many occasions our systems function in three eight-hour shifts where a split second is vital. Thereby, you should pick the cool off time – enough time for cooling the solder bar before it is lifted up in the soldering point.
Tabletop system BLS-50
Our Hot Bar Soldering system BLS-50 is actually a complete system for direct utilization in the ongoing production. The Recent Bar Soldering station is founded on a universal mounting in the base plate where various equipment can be applied. We can also construct and provide the ideal mounting setup. In the simplest form you send us the various components which should be soldered therefore we construct the compatible mounting plate to suit your needs.
With all the included control electronics all required parameters could be set. The apparatus is controlled having a two-button operation and also the whole device corresponds to the present CE safety standard. To implement the Soldering system a 380 Volt (16A) power supply and compressed air (6-8 bar) is essential. The machine is made up of the tabletop and the associated power supply:
Upon request the Bar Soldering station BLS-50 (model BLS-50-D)is offered that enables the strain being monitored electrically. In cases like this, a precise control unit for 15dexopky with all the prescribed target pressure values is supplied. This special function is essential for all processes where materials are soldered to very sensitive substrates along with monitoring and documenting all production parameters permanently. The control electronics which can be included enables the setting from the following parameters:
Inside our 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 development and delivery time. Through 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 trouble for our system. If you would like modify the LED Soldering Machine our recommendation is 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 within your company.
