检测中心

Of course we start with the functional testing of the PCBA, right after it comes out of the SMT line but before it gets assembled into mechanical enclosures. Then we have the Automated Optical Inspection (AOI) and Automated X-Ray Inspection.(AXI) is used in multiple places along the production and assembly line. You might, for example, use AOI after applying solder paste to your PCB but before you place components, to verify correct solder paste placement.

Optical Inspection only catches faults that are visible on the surface of a board, so you won’t be able to see the solder joints underneath those parts to verify good connection to all of the part’s pins. This is where AXI comes into play. AXI offers some great insights into what’s going on in your circuit board. You get to see inside your board, inside the parts on your board, and all of the solder joints, even the hidden ones, to truly verify that all of the connections have been properly made during the assembly process.

自动光学检测

当然,产品从SMT到功能测试、装配之前,我们有多个工位使用自动光学检测和自动X射线检测。例如,在PCB板印刷锡膏之后,使用自动光学检测设备确认锡膏印刷的效果。

自动X射线检测

光学检测只能捕捉到线路板表面可见的异常,无法看到隐藏在元器件底部的焊接状况。这个时候,就需要使用自动X射线检测设备,确认元器件底部的焊点或引脚部位的焊接状况是否良好。
