How to test and inspect industrial connectors
Industrial connectors are a very common connector product in the electronics market, but among all the current connector product types, the transmission capacity of industrial connectors is the strongest, and can be widely used in many fields. Used in communication networks, power systems, industrial automation, medical equipment, office equipment, smart home appliances, military manufacturing and other industries. This article mainly explains the industrial connector test and inspection.
Test inspection of industrial connectors:
1. Observe that the loading voltage on the industrial connector should not exceed 50% of its rated voltage
2. The installation size of the industrial connector. For the plug-in header, the length of the soldering feet on the soldering PCB requires that the exposed part of the PCB board is greater than 0.5MM
3. For industrial connectors with high precision, when PCB space permits, try to choose models with a little positioning to facilitate the operation when manual soldering is required
4. Check if there is a foolproof design
5. Check whether the materials used in industrial connectors contain lead
6. Small-sized industrial connectors, with low contact pressure, and low current and voltage applications, it is recommended to use gold-plated or silver-plated connectors to avoid film resistance affecting signals
7. Pay attention to the height of the industrial connector after mating, whether it meets the welding height of the components around the PCB. The mating height must be greater than the soldering height of the components around the PCB, and ensure that there is a certain margin to ensure that no interference occurs. Special attention should be paid to the possible height errors of the components after PCB soldering.
