Analysis Of Needle Pin Adapter Dynamics In IGBT Module Endtest Process

Abstract

Needle Pin is a needle located on the dynamic adapter and functions to provide voltage to the IGBT module pins during the Endtest process. Many testing processes are not completed on time because some processes do not run according to schedule, especially in the Endtest process due to delays which result in long downtime, one of which is due to problems with testing dynamics. Damage to the dynamic adapter is mainly burnt and jammed needle pins. The author uses the fishbone method/Ishikawa diagram to find out the factors and root causes that cause burnt needle pins. The main root cause in this research is contaminated pins module. This research found that the value of P1 The average machine downtime before repair was 68.83 minutes, min 30 minutes and maximum 115 minutes and the percentage was 71.69%. And the value of P2 The average machine downtime after repairs was 55.08 minutes and the min was 20 minutes and the maximum was 85 minutes and the percentage was 57.37%. Based on the matrix, the comparison range for P1 and P2 is 14.32%.
