FR4 material is the best cost effective material for multilayer PCBs, compared with other based material, its reliability is also much better. However, in order to reduce the cost of PCBs, there are some companies using low quality FR4 material. The reason is that this kind of PCB manufacturer is usually small and they can not have quantities to reduce the cost, in order to survive in the market they have to reduce the cost. And for prototype, using low quality FR4 is also a very effective way to reduce the cost.
Using low quality FR4 and cheaper material seems as a good way if the PCB board's quality is acceptable, if you want to control the quality better, please think it twice before you make the final decision. Big PCB manufacturers only use high quality FR4 material, for it is easier to control the quality of PCB products.
Flytop Circuit Limited is a leading PCB manufacturer specializing in PCB manufacturing with many years experiences, the company use high quality FR4 material to control the quality, especially in mass production.we reduce the cost by going really high volumes, the prices of high quality FR4 at high volumes are not necessary higher than that of the low quality FR4 at low volumes.
