Using these micro B USB connectors is easy. First, identify the through - hole mounting tabs on the connector and align them with the corresponding spots on your PCB. In an SMT line, just apply paste over the through holes and let the pads solder in place. When handling, be gentle as although they're sturdy, rough handling can still cause damage. For maintenance, keep them in a dry and clean place to prevent rusting. Avoid exposing them to extreme temperatures as it may affect their performance. If you're using them in a project, double - check the connections to ensure a stable electrical flow.
