AOI Test OEM PCBA Manufacturering Semiconductor PCB One Stop Fabrication
Semiconductor boards differ from most other custom PCBAs because they are not intended for a single application. Instead, these boards are meant to be applied widely and across many different industries. The boards may be used as samples to display capabilities, or they may be installed into a larger system for faster bringup. When designing and building semiconductor boards, reliability is the key attribute, regardless of how the board is utilized.
Semiconductor PCBA Manufacturing Service Requirements
Build Flexibility
Semiconductor PCB must often transmit, receive, and process various
signal types, interconnect using different types of connectors, and
perform in unique environments. Therefore, your CM must excel in
all types of board building, and they must meet IPC Class 1, 2, and
3 performance level standards. Additionally, they should be able to
manufacture non-standard form factors.
Secure Component Procurement
For turnkey, your CM is responsible for procuring components (with
the possible exception of exotic components) from a secure supply
chain that is free of counterfeits and obsolete components.
Quality Assembly
Semiconductor PCB reliability is only attainable with quality
assembly. Your board’s ability to last throughout its intended
lifecycle depends on high-quality solder connections for both SMDs
and through-hole components.
Process Agility
Design changes may be required to add or improve functionality or
meet customer demands. Time may be of the essence here, and your CM
needs an agile manufacturing process that can incorporate changes
quickly with minimal process adjustments or the need for additional
equipment.
Accurate and Accessible Documentation
As semiconductor PCB may experience multiple revisions or
integration into other design projects, accurate and thorough
documentation is mandatory.
While other considerations may arise when assessing a CM’s ability to meet your turnkey semiconductor service needs, ensuring it can satisfy the requirements listed above is essential.

FAQ
Q: What is the difference between the HDI board and the general
circuit board? CESGATE: Most of HDI use laser to form holes, while general circuit boards only use mechanical drilling, and HDI boards are manufactured by the build-up method (Build Up), so more layers will be added, while general circuit boards are only added once. |
Q: What are the types of solder mask? CESGATE: There are traditional epoxy resin IR baking type, UV curing type, Liquid Photo Imageable Solder Mask and Dry film solder mask. Currently, the liquid solder mask is the main type. |
Q: What are the common substrates of CESGATE? A:Tg-140: ISOLA FR402 / NAN-YA NP-140 Tg-150: ISOLA IS400 / NAN-YA NP-155 Tg-170~180: ISOLA 370HR / NPN-YA / NAN-YA NP-175F |
