Introduction: Optimizing PI tape application locations in 5G PCB assembly is critical to maximize its protective benefits. This guide identifies key areas where strategic PI tape placement enhances 5G device durability and manufacturing efficiency.
Targeted Application Zones:
Gold Finger Wrapping:
Method: Cover gold fingers with PI tape during reflow to prevent solder bridging or oxidation.
Benefit: Maintains gold contact integrity for millions of mating cycles.
Thermocouple Attachment:
Location: SMT furnace monitoring points.
Purpose: Secures thermocouple wires to measure real-time temperatures, ensuring process control.
Flexible Circuit Board (FPC) Fixation:
Scenario: During SMT pick-and-place, PI tape stabilizes FPCs on fixtures to prevent misalignment.
High-Voltage Connector Isolation:
Application: Wrap connectors to insulate terminals from stray currents, vital for 5G’s high-power modules.
Best Practices Checklist: ✅ Clean PCB surfaces before tape application. ✅ Use precision cutters for accurate PI tape shapes. ✅ Remove tape post-welding within 24 hours to avoid adhesive curing.
ROI Analysis: Implementing targeted PI tape placement in 5G assembly lines can save up to $50,000/month in rework costs for medium-sized manufacturers.
