SMA connector is a widely used semi-precision ultra-miniature RF and microwave connector, which is a very commonly used connector. Most RF manufacturers will provide this type of connector. To make a high-quality SMA connector, we need to ensure its electrical performance, but the appearance inspection is also a key aspect. The appearance of SMA connectors does not seem to affect their electrical performance of use. However, if the appearance of improper control, such as the appearance of scuffing, SMA connector products will accelerate the oxidation and directly affect the life of the product. Therefore, we need to check the appearance of SMA connector products. Here we will take SMA connector RG174 from LenoRF as an example.
Here is the content list:
l A-level surface inspection
l B-level surface inspection
l C-level surface inspection
A-level surface inspection
1、The first step is to check if there is shrinkage in the locating pin of SMA connector RG174 and impurities in the 4-hole-flange jack.
2、The second step is to check the PTFE of SMA connector RG174 for back pressure.
3、The third step is inspecting the contact table of the SMA connector bore for damage.
4、The fourth step is to inspect the contact surface of the SMA connector for crushing, scratching, or bruising.
B-level surface inspection
1、The first step is to inspect the 4-hole-flange jack surface of SMA connector RG174 for material shortages, bumps, knife marks, and chamfers.
2、The second step is to check 1-6 inspection points from port to tail to confirm that the ports of SMA connector RG174 are free of material shortages.
3、The third step is inspecting the threads and milled surfaces of SMA connector RG174 for bumps, return grooves for turning patterns, and thread changes and tails for cracks.
4、The last step is to check the coating of SMA connector RG174 for oxidizer, copper leakage, water stain printing, and so on.
C-level surface inspection
1、The first step is to check the tank for damage, deformation, or material shortage.
2、The second step is checking whether the surface of SMA connector RG174 has knocks, scratches, and obvious knife marks during processing.
3、The third step is to inspect whether the tail of SMA connector RG174 is deformed, broken, or shorted during machining.
4、The fourth step is to inspect whether the daughter and female pins of SMA connector RG174 are blocked, eccentric or damaged.
5、The last step is to check the coating for oxidation, copper seepage, water stains, and so on.
