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°.
Кроме того, if it is impossible to see clearly under normal circumstances (например, 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 Diameter | Инспекция | Arbitration |
| ＞1.0мм(0.039в) | 1.75Х | 4Х |
| ＞0.5至1.0мм(0.020-0.039в) | 4Х | 10Х |
| 0.25至0.5мм(0.00984-0.020в) | 10Х | 20Х |
| ＜0.25мм(0.00984в) | 20Х | 40Х |
