FAQ:
1. How do ACCPCB ensure quality?
Our high quality standard is achieved with the following.
1.1 The process is strictly controlled under ISO 9001:2008 standards.
 1.2 Extensive use of software in managing the production process
 1.3 State-of-art testing equipments and tools. E.g. Flying Probe,e-Testing, X-ray Inspection, AOI (Automated Optical Inspector) .
 1.4.Dedicated quality assurance team with failure case analysis process
 
 2. What kinds of boards can ACCPCB process?
Common FR4, high-TG and halogen-free boards, Rogers, Arlon, Telfon, aluminum/copper-based boards, PI, etc.
 3. What data are needed for PCB production?
PCB Gerber files with RS-274-X format.
 5. 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.
