PVC End Plug and Tube shape retention under heat and force?

Click For Summary
SUMMARY

The discussion centers on the deformation of PVC end plugs and tubes under heat and mechanical stress, specifically in the context of semiconductor packaging. Mai, a supplier quality engineer, reports issues with warpage and loose end plugs upon receipt of units. Experts confirm that PVC is susceptible to heat and UV exposure, which can lead to deformation. The type of PVC, whether Schedule 40 or thin wall, is crucial in understanding its performance under these conditions.

PREREQUISITES
  • Understanding of PVC material properties
  • Knowledge of heat and UV effects on plastics
  • Familiarity with packaging standards in semiconductor industries
  • Basic concepts of mechanical stress and deformation
NEXT STEPS
  • Research the thermal properties of PVC, specifically Schedule 40 PVC
  • Investigate UV resistance treatments for PVC materials
  • Learn about best practices for packaging semiconductor components
  • Explore alternatives to PVC for high-temperature applications
USEFUL FOR

This discussion is beneficial for quality engineers, packaging specialists, and professionals involved in semiconductor manufacturing and materials science, particularly those dealing with PVC applications.

PVC End Plug and Tube shape retention under heat and force??

Hi, I'm Mai from one of the semiconductor company. I'm in charge in supplier quality enginnering. I have an issue happened in my customer side where, whenever they received the unit from us the unit will spill out from the packing.

The packing we used are the PVC tube and end plug. When we received back the defect packing the tube was already warpage and the end plug already getting loose. Here I need an expert advice on the the PVC characteristic. Is it really easily deform?

if there anyone that have this issue before appreciate if you can share with me what is the solution.

I am not an engineer, but as a Master Plumber, I consider myself an expert on PVC piping.

By end plug, are you referring to a PVC cap or a screw-in cleanout plug?

PVC is very susceptable to heat and long term exposure to UV. Is this Schedule 40 PVC or thin wall pipe?

A picture would assist.
