To choose a PCB manufacturer in China, you have to take lots of factors into consideration, such as defective rate, production line quantity, etc. Among them, EPCB regards that a good final inspection of flatness really matters, otherwise warping can affect PCB performance to some extent. In this article, EPCB will discuss how China PCB manufacturer handle PCB warping issue?
Most PCB manufacturers in China are used to baking warping in oven. Usually the oven is set back under pressure, and the temperature can reach 150℃. And then take 3 to 6 hours to cool down the PCB in nature under pressure. In addition, it is necessary to check those PCBs, different PCB manufacturers use different final inspection method.
Hope it is useful for you.
