SMT General inspection standard (Part II)

Leadsintec will design a quality control product inspection based on product specifications and requirements you provide that fits within your budget.

Inspect Condition:

Put the SMT component semi-finished product under normal illumination that brightness above 800LUX, 1M directly below or 1M of 45W fluorescent lamp, and check it within 5 seconds at a distance of 45CM from the SMD semi-finished product in the direction of 45°-135°.

In addition, if it is impossible to see clearly under normal circumstances (for example, the component feet are dense and the body is too small), a magnifying glass should be used for observation. The specific requirements are as follows:

Land Width or Land DiameterInspection Arbitration
1.0mm(0.039in)1.75X4X
0.51.0mm(0.020-0.039in)4X10X
0.250.5mm(0.00984-0.020in)10X20X
0.25mm(0.00984in)20X40X
