How to detect board-to-board connectors

　　Before we choose an ultra-small connector, we must check whether the connector has all the performance we need, and carefully test it to ensure its strength and durability. Next, I will introduce how to detect board-to-board connectors in detail.

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

　　2. Board-to-board connector device ruler For inserting headers, the length of the solder feet soldered to the PCB requires that the part of the display PCB exceeds 0.5mm.

　　3. In high-precision board-to-board connectors, when the PCB space is promised, try to choose the model with positioning pins to facilitate the operation when manual soldering is required.

　　4. Check if there is a foolproof design.

　　5. Check whether the materials used in the board-to-board connector contain lead.

　　6. Small board-to-board connectors have low contact pressure. In the case of low current and voltage, it is recommended to use gold-plated or silver-plated connectors to avoid the influence of film resistance.

　　7, pay attention to observe the height of the board and the board connector after cooperation, whether it meets the welding height of the surrounding parts of the PCB circuit board. The cooperation height must be greater than the welding height of the components around the PCB circuit board, and a certain margin should be ensured to ensure that no interference occurs. Pay special attention to the height error of the components after the PCB circuit board is soldered.
