制造过程

它如何被制造

CNC milling and turning → deburr and clean → copper / nickel / gold plating → final dimensional and plating-thickness inspection.

应用场景

它被用在哪里

Laser package housings carry the pump diode, optics and thermistor of a laser module. This demo entry illustrates the product template: a Kovar or SUS304 body with an oxygen-free-copper or tungsten-copper base, machined seats for the submount and a Cu–Ni–Au plating stack for solderability. Replace with a verified product entry.

FAQ

Frequently asked questions

Which plating purity grades are available?

Soft gold Type III ≥99.9%, hard gold Type I ≥99.7%, hard gold Type II ≥99.0%.

Can the base be tungsten-copper?

Yes — base plates are offered in OFC or tungsten-copper per thermal requirements.
