Cleaning Avoid using any unspecified chemical solvent to clean LED For example, Trichloroethylene, Chlorosen, Acetone, and Diflon S3MC. Any cleaning method can only be taken under normal temperature in one minute or less if it is required. Alcohol is the one recommended for cleaning.
Forming Any forming on lead pin must be done before soldering, not during or after soldering. Avoid applying any stress to resin in order to prevent the epoxy fracture and break on bonding wire. While forming, please use a tie bar cut or equivalent to hold or bend the pin. 2mm from the base of resin is the minimum distance for the place bending the lead pin. Avoid bending the lead pin at the same point twice or more.
Soldering Pin hole pitch on PCB must match lead pin pitch so as not to cause any stress on lead wires. No stress can be applied to lead pins when they are heated, otherwise disconnection may occur. Three minutes are necessary for LED to cool down to normal room temperature.
