The analysis whether a board is perfect or features issues can be drawn by different algorithms applied by AOI. When it comes to simple applications inspection, pixel-counting algorithm is used containing the following methods:
• Template matching - Template-matching method, also called area-based method or correlation-like method, has been popular for a couple of decades. Based on pixel-by-pixel method, a small template is applied to a large inspection image through sliding template window. Then, normalized cross correlation (NCC) will be calculated between the template and inspection image. The larger the value of NCC is, the higher matching between them will be.
• Object recognition - Object recognition conforms to the same principle as view method in that difference is observed through comparison between an ideal image and the captured image of an object.
• Blob analysis - Blob analysis refers to a process during which the object is separated from the background first. Then with a pixel-based image applied, a blob is generated through grouping of object pixels to inspect issues of objects.
Shenzhen Yideyi Technology Co., Ltd provide SMT Pick and Place Mounting Service for Surface Mount Components (resistors, capacitors and ICs etc) on PCB and LED MCPCBs
Q1. How can we ensure our information should not let third party to see our design?

Copper thickness:Surface finish:
Solder mask color:
We are able to handle Small as well as large volume production with flexibility.
Q5. With payment terms do we accept?
For sample order or small batch, we suggest you to use Pay-pal and Western Union.For mass production batch, we suggest you to use T/T.
Q6. How can we guarantee you receive an good quality product?
For PCB, we will use Flying Probe Test, E-test etc. for it.
For PCBA, we need you to offer us a method or test fixture for the function test.Before that, our inspectors will use microscope and X-ray to check the IC footwelding or bad solder etc.
