Process information for truck dashboards:
Test stand: The first 300 sets are not tested and burned. The material and PCB board are first produced at 1000pcs, and the assembly is first made 300pcs for customer test confirmation.
Solder paste requirements: Ag0.3/Cu0.7/20-38uM
Reflow soldering temperature setting: PCBA welding maximum temperature is 245-250 °C, super 230 °C welding time control 40-60s
Special requirements: On-site protection is required when soldering LCD, PCBA cannot be stacked
Component shearing requirements: LCD screen cutting feet need to be cut and cut, pay attention not to damage the PCB board, need to paste black electrical glue after cutting
PCBA cleaning method: LCD screen solder joints do not need to be cleaned, use cotton swabs, tweezers and other tools to remove tin beads tin slag; when cleaning other post-welding materials, be careful not to apply cleaning agents to the LCD screen, or vice versa LCD screen scrap
