High Functional PWB Technology
Types of PWB materials
Optimum materials for high-heat resistance can be proposed according to customer's requests based on our reliability test data of plated through holes in PWBs made with various types of materials.
Types of Solder resist
Possible to use Solder resist for High-heat resistance.
Good adhesives can be kept after temperature cycling tests (test condition : -40 ºC ⇔ 150 ºC dwell time 30min., surface finish : solder leveling)
Types of Surface finish
Possible to use OSP of high-heat resistance type.
|OSP (Normal type）||Low||High||Superior||$$||OK|
|OSP (high-heat resistance type）||High||High||Superior||$$||OK|
|Lead-free solder leveler||High||Low||Superior||$$$||NG|
