How is the four layer pcb made

Our quality control
Quality Control
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
Micro BGAs
Chip scale packages
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
Cuatomer inquiry requirement
