Manufacturing Process
Power Pack
1. Die Bonding Process
Die bonding process is preprocedure of next soldering process.
2. Soldering Process
The soldering boat loaded with material is introduced into soldering furnace by conveyor.
3. Molding and Curing Process
Put the jointed semi-product in a forming mold, and then apply mold press to inject epoxy resin into forming mold.
4. Plating Process
After trimming/froming, the surface of terminal need to be electroplated by a Sn layer, which is available to solderability improvement and to prevent from oxidation.
5. Trimming / Forming
The terminal of leadframe need to be trimmed and formed as specified dimensions with trim/form machine.
6. TMTT Process
Test electrical characteristics of finished products successively each time by TMTT machines.
