The BSOM (Beam Shaping Optical Module) patented technology takes the energy of a spot laser and turns it into a uniformly distributed area laser, the company explained. The uniformity of the energy is greater than 95 percent. This means that the energy of the spot laser is spread out evenly allowing for the same amount of energy density over the entire area to be soldered. This enables the proper coalescence, wetting, intermetallic formation to take place forming the final electronic interconnect or solder joint. The company says it designs and manufactures this technology in-house.
The new rework system automatically attaches and detaches mini-LEDs on mini-LED substrates. When applied to the production line of backlight panels of tablet PCs and notebook PCs, Laserssel says it provides a rework yield rate of 99 percent or higher, providing great cost savings to the panel production line.
