CT DMC ?
Co-Planar
Light transfer type: face to face
Hard process than Co-planar
Light transfer type: reflection
The easiest coupler process
The coupler construction design have to follow the safety house rule. Over
tolerance, and bad process control will be caused isolate fail.
Coupler FMEA
The distance through isolation of coupler is
≧0.4mm
The product LongCreepage is one
of the super thin package. All the
tolerance are restricted by the
package limit and safety request.
High of wire bond also one of the
key inspection.
Confidential
The through distance of CT DMC ?
package is trustworthy due to the
distance has done when the lead
frame forming. There is no need to
control by process.
