Pcb process information:
Pcb manufacturing process: surface assembly lead-free process
Circuit board over-boiler experiment: All plastic-molded patch materials must be reflow soldered (except J1, J2, J3)
Solder paste requirements: Ag3.0/Cu0.5/20-38uM
Double-sided patch: first paste the BOT surface (U5)
The patch is changed to hand soldering: J1, J2, J13 materials are not resistant to high temperatures and require manual soldering.
Reflow soldering temperature setting: welding maximum temperature is 245-250 °C, super 230C welding time is controlled 40-60S.
Circuit board cleaning method: The washing water cannot corrode to the internal contacts of the connector.
Pcb product packaging: bubble roll veneer packaging.
