FAQ:
1. What kinds of boards can ACCPCB process?
Common FR4, high-TG and halogen-free boards, Rogers, Arlon, Telfon,
aluminum/copper-based boards, PI, etc.
2. What data are needed for PCB production?
PCB Gerber files with RS-274-X format.
3. What’s the typical process flow for multi-layer PCB?
Material cutting → Inner dry film → inner etching → Inner AOI →
Multi-bond→ Layer stack up Pressing → Drilling → PTH → Panel
Plating → Outer Dry Film → Pattern Plating → Outer etching → Outer
AOI → Solder Mask → Component Mark → Surface finish → Routing → E/T
→ Visual Inspection.
4. How many types of surface finish ACCPCB can do?
the leader has the full series of surface finish, such as: ENIG,
OSP, LF-HASL, gold plating (soft/hard), immersion silver, Tin,
silver plating, immersion tin plating, carbon ink and etc. .. OSP,
ENIG, OSP + ENIG commonly used on the HDI, we usually recommend
that you use a client or OSP OSP + ENIG if BGA PAD size less than
0.3 mm.
