Understand the board-to-board connector test inspection

Hello everyone, I am the editor. Board-to-board connector test inspection. Let’s take a look together below;

1. Observe that the voltage loaded on the board-to-board connector should not exceed 50% of its rated voltage.

2. Board-to-board connector installation size For plug-in headers, the length of the soldering feet soldered to the PCB requires that the exposed part of the PCB is greater than 0.5mm.

3. For high-precision board-to-board connectors, the model with positioning pins should be selected as far as possible when the PCB space permits, which is convenient for manual soldering.

4. Check if there is a foolproof design.

5. Check whether the material used in the board-to-board connector contains lead.

6. Small-size board-to-board 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 from affecting signals.

7. Observe the height of the board-to-board connector after mating, and whether it meets the soldering 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.
