Conformal coating
Both dip-coating and vertical spray coating is available. Protecting non-conductive dielectric layer that is
applied onto the printed circuit board assembly to protect the electronic assembly from damage due to
contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments.
When coated, it is clearly visible as a clear and shiny material.

Functional testing


Quality Processes:
1. IQC: Incoming Quality Control (Incoming Materials Inspection)
2. First Article Inspection (FAI) for every process
3. IPQC: In Process Quality Control
4. QC: 100% Test & Inspection
5. QA: Quality Assurance based on QC inspection again
6. Workmanship: IPC-A-610, ESD
7. Quality Management based on CQC, ISO9001:2008, ISO/TS16949


Design file format:

1. Gerber RS-274X, 274D, Eagle and AutoCAD's DXF, DWG
2. BOM (bill of materials)
3. Pick and place file (XYRS)

Advantages:

1. Turnkey manufacturing or quick-turn prototypes
2. Board-level assembly or complete system integration
3. Low-volume or mixed-technology assembly for PCBA
4. Even consignment production
5. Supoorted capabilities
