(one time only) pre - heat pre - heat time solder wave soldering time 100c max. 60 sec. max . 260c max. 5 sec. max. note: excessive soldering temperature and/or time might result in deformation of the led lens or catastrophic failure of the led . ir reflow is not suitable process for through hole type led lamp product . part no . : ltl - 4231nldllc - dl p age : 7 of 10 bns - od - c131/a4
