Piranha module is welded with three led piranha beads onto the PCB . (Piranha module’s led bead have four feet which are more than 2 feet than normal 5mm led. There are fixed gap between four feet and their welded place of PCB , this design is good for cooling and cooling effect better than normal led . The working current can be reach to 40MA which is lager than normal LED with 20MA , that’s why it is with high brightness than normal led )
Module Point glue dispensing process
Paste---reflow soldering----Electrical test ---- Board split ---- Put on the screw -----whole series of module bumps ----- whole series of electric testing module ----- Glue dispensing ----package
