PEI RF Welding and Reflow
Problem Phenomenon
In RF welding and reflow assembly of PEI device components, poor bonding and thermal damage occur; connection quality is unstable.
Cause Analysis
PEI can undergo RF welding and reflow, providing a simple connection method for device components; but the parameter window needs to match; material state affects welding quality; thermal management prevents damage.
Solution
①Optimize RF welding parameters to match the material; ②manage the state of welding surfaces; ③control the reflow temperature curve; ④verify connection strength.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PEI RF connection is an advantage in medical assembly; parameter matching is the key; verification ensures reliability.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
