(one time only) no closer than 2mm from the base of the epoxy bulb pre-heat pre-heat time solder wave soldering time dipping position 100c max. 60 seconds max. 260c max. 5 seconds max. no lower than 2mm from the base of the epoxy bulb note: excessive soldering temperature and/or time m ight result in deformation of the led lens or catas trophic failure of the led. ir reflow is not suitable proce ss for through hole type led lamp product. 6.6. drive method an led is a current-operated device. in order to en sure intensity uniformity on multiple leds connecte d in parallel in an application, it is recommended that a current limit ing resistor be incorporated in the drive circuit, in series with each led as shown in circuit a below. circuit model (a) circuit model (b) led led (a) recommended circuit (b) the brightness of each led might appear differe nt due to the differences in the i-v characteristic s of those leds.
