Clean Pad Drop Error Abnormality

Pin-Jet helped the customer determine the reason for the abnormality

The customer gave the feedback that the clean pad would not fall after the vacuum in the NEST was broken; after confirmation by Pin-Jet, it was found that there was inverted round corners inside the NEST, but the clean pad had a right-angle exterior, which caused interference.

Problem Description

✔ Abnormal problem: Solve the problem of the clean pad getting stuck in the clamp and unable to be lowered when trying to lower it for cleaning
✔ Package type: BGA
✔ Target: Solve abnormal problems

Problem Confirmation

	Clean Pad	Clamp
Entity		※ The Clean Pad originally had a right-angle design and therefore interfered with the Clamp R angle; currently there are wears and tears.
Actual size	15.57 x 15.57mm	15.71 x 15.72mm
Conclusion	The Clean Pad Lid is a right angle and the Clamp Lid is a R angle; they do not match and therefore when lowered for cleaning, the clean pad gets stuck in the clamp and cannot be lowered. It is recommended to change the design of the Clean Pad Lid to improve the current problem.

Implementation Verification

	Before Modification	After Modification
Entity	※ The new sample had right-angles, and the image is the entity after use.
Verification conclusion	Before modification, the clean pad got stuck in the clamp and cannot be lowered when trying to lower it for cleaning.	After modification, the Clean Pad Lid was changed to rounded corners, and the samples all worked normally after verifying the modification.

Conclusion:

Before modification, the clean pad got stuck in the clamp and could not be lowered for cleaning.
After modification, the Clean Pad Lid was changed to rounded corners, and the samples all worked normally after verifying the modification.
