01 / QFN package workpiece
QFN Package Deflashing
Molding flash remains on the workpiece surface after packaging and needs removal around the contacts.


The processed comparison shows the contacts and surrounding surface after deflashing.
Automatic buffing equipment for IC packages and ceramic substrates, including package deflashing and ceramic-substrate copper-surface leveling and thinning.

HGT / APPLICATION RESULTS
HGT series processing examples. Actual results depend on materials, workpieces and equipment configuration. These photographs do not represent HGT-421 specifications or performance.
01 / QFN package workpiece
Molding flash remains on the workpiece surface after packaging and needs removal around the contacts.


The processed comparison shows the contacts and surrounding surface after deflashing.
02 / Laser-drilled substrate
Removes residual slag around hole edges after laser drilling.


Before/after photographs compare the hole edges following slag removal.
03 / Patterned substrate surface
Buffing and leveling the patterned surface prepares the workpiece for subsequent processes.


The comparison shows changes to the patterned surface before and after buffing.
