7 Common PCB Testing Methods
Electronic Contract Manufacturers (tdt-ele) offer a variety of PCB test methods, but the seven main types include:
· Visual inspection
· In-circuit testing (ICT)
· Flying probe testing(FPT)
· Automated optical inspection(AOI)
· X-Ray inspection
· Burn-in testing
· Functional testing (FCT)

Factors That Affect PCB Fabrication Cost
There are a variety of factors that affect the cost of manufacturing a PCB. Generally, the seven most influential factors are board size, number of layers, quantity, type of material used, surface treatment, hole size, custom specifications.

WHAT IS THE PCB FABRICATION PROCESS
PCB fabrication is the process of creating the bare boards that will serve as the foundation for printed circuit board assembly.The printed circuit board (PCB) manufacturing process is an extensive and intricate procedure, where each step must be carefully executed to ensure optimum performance of the finished board.

How to Properly Store Your Printed Circuit Boards
Factors affecting PCB storage cycle include PCB surface coating type, printing board type, storage environment, packaging material type, etc. If these factors are handled well, PCB can be stored well and the service life of PCB can be extended.

Why FR4 is Used for Most PCBs?
FR4 material is the most common grade dielectric material that is used in the fabrication of circuit boards. General single, double sided and multilayer PCB boards are made with it! Because of its high strength and flame retardant properties, most circuit boards will choose FR-4 as the substrate.

The Different Types of PCBs
The different types of printed circuit boards mainly include the following
· Single-Sided PCBs
· Double-Sided PCBs
· Multilayer PCBs
· Rigid PCBs
· Flex PCBs
· Rigid-Flex PCBs
