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.

Complete box build
Complete 'Box Build' solutions including materials management of all components, electromechanical parts,
plastics, casings and print & packaging material

Testing Methods
AOI Testing
Checks for solder paste
Checks for components down to 0201"
Checks for missing components, offset, incorrect parts, polarity
X-Ray Inspection
X-Ray provides high-resolution inspection of:
BGAs
Bare boards
In-Circuit Testing
In-Circuit Testing is commonly used in conjunction with AOI minimizing functional defects caused by
component problems.
Power-up Test
Advanced Function Test
Flash Device Programming
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)
