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.

4. 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.

5. How many types of surface finish ACCPCB can do?


O-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.

6. What are the main factors which will affect the price of PCB?


Surface finish;

Board thickness, Copper thickness;
Technology difficulty;
Different quality criteria;
PCB characteristics;
Payment terms;


7. How to you make the impedance calculation?


The impedance control system is done using some test coupons, the SI6000 soft and the CITS 500s equipment
