The laser welding material used in LED lighting circuit was developed by Tian Cun

Where Japan Tamura production "in the fourteenth session of the printed circuit board of the exhibition (16 January to 18 days in Tokyo have held the International Conference and Exhibition Center), exhibition can make the welding process automation of laser welding materials LED lighting and intelligent mobile phone circuit board etc..

For the LED lighting circuit board is called "SP-NALT" varieties, packaging equipment "to" roll "in the process of PET thin film circuit board LED chip package specifically for Nisshinbo precision machines NALT-01 development. The use of the device can be used without the use of reflow soldering oven LED chip, so the production line area and electricity tariffs than the original reduction.

In the PET on the circuit board facing laser welding is subject, solder materials generally at 220 DEG C will melt, and PET heat temperature lower than the temperature, so it is necessary to develop in laser welding short time rapid heating is not easy to scatter the material. In addition, due to the use of coated tin coated solder materials must ensure liquidity, it also improved the flux.

Changing the manufacturing process of fluorescent lamp type LED lighting

For a variety of intelligent mobile phone circuit board welding, developed the solder ball flying laser welding control around 0.3mm solder paste LSM20". Using the previous solder, solder ball flying levels reached about 1.2mm, for high packing density intelligent mobile phone circuit board, will be very difficult to weld. Tamura produced by using special thermoplastic resin, and the resin in molten solder hardening, suppress the flying ball.

The use of new welding materials, the idea is used to make the circuit board on the headphone jack and connectors and other large size components of the welding automation. At present, the industry generally through reflow welding parts, so large size components need to increase the strength of the welding part of the manual welding. In addition, the welding material is also expected to be used to correct the parts of the dislocation, as well as shielding parts such as three-dimensional welding.
