This article we will discuss why some companies still use low quality FR-4 PCB base material to produce.
If you have done some research, you will find this is a very complex problem.
Many differing reasons to resulting in use low quality FR-4 PCB base material.
Emma has list top 3 reasons that may use low quality FR-4 PCB base material.
Small PCB manufacturers likely use low quality FR-4 PCB base material
The simple reason is that small PCB manufacturers just can meet small customers’ requirement.
Most of those PCB requirement is quite small and can’t produce mass production to reduce the cost.
In order to survive in the global PCB market, most small PCB manufacturers have to use cheaper PCB base material.
The second reason is prototype PCB produce
You know the prototype PCB board is so special to mass production PCB produce.
Some of PCB manufacturers do not provide prototype PCB, and some company where specialized produce the prototype board.
So they want to use low quality FR-4 PCB base material to cast down.
Most of time the quality control not in prototype PCB board.
Third is related to PCB market share
What is your PCB supplier PCB market share, high end or not?
If you choose high end PCB manufacturers, they must use of best FR-4 PCB base material to produce.
