What aspects should be paid attention to when purchasing board-to-board connectors and how to maintain them daily
The internal metal pin components of the board-to-board connector are mostly composed of some electroplated parts. Therefore, in the storage package of the connector, the connector must be sealed and not directly exposed to the air to contact, otherwise the connector will be affected later. Affected by the humidity of the air, the inside of the component is damp and oxidized. Then let's take a look at what aspects need to be paid attention to when choosing a board-to-board connector and how to maintain it daily.
1. Observe that the load voltage of the board-to-board connector cannot exceed 50% of its rated voltage.
2. The mounting size of the board connector is a plug, and the length of the soldering foot soldered to the PCB needs to be exposed to the PCB board section greater than 0.5mm.
3. For high-precision board-to-board connectors, try to choose the model with positioning pins when the PCB space allows, so that it is convenient to operate when manual welding is required.
4. See if there is a foolproof design.
5. Whether the materials used contain lead.
6. Contact resistance: small size board-to-board connector, low contact pressure, low current and low voltage, it is recommended to use gold-plated or silver-plated connectors to avoid the film resistance from affecting the signal.
7. Pay attention to observe the height of the board-to-board connector after the connector and whether it reaches the soldering height of the components around the PCB. The matching height of the circuit board must be greater than the soldering height of the components around the PCB to ensure a certain margin and ensure no interference. In particular, it should be noted that after the PCB is soldered, higher errors may occur.
