In the past year I was responsible for developing and leading a Team focused on AOI, Evaluation, Justification, and with a full ROI required, supporting a HMLV manufacturing environment. If you have in these economic times the additional resources t

Start with a definition of what you expect the AOI to achieve at each station. Will your in-line machine be post print? Place (pre-reflow) or post reflow? Rather than buy one very expensive machine to put at the end of the line, maybe a couple of

Good Morning Roger, The Mirtec's can be adjusted to lower your false call rate. This can be done by reducing the matching percentage for each componnent but the result of this action is that the machine becomes less selective. If you lower them too

Russ, u mean excess flux causes "blow hole" defect?

John, There is one process issue that occurs with the larger BGA packages which have coplanarity near the high end of the .2mm spec.. The defect is commonly referred to as "ball in cup" and "head in pillow". It is an open solder connection whereby th

dear sir i am new for aoi section,my work will be teaching of aoi defect and related to programming, want to know how to make program easily in mirtec 4.1.1 and what are the different standard which we must understand.

methos1979, 1. Mirtec, Marantz 2. Koh Young, Orbotech, Mirtec 3. Koh Young Zenith 4. Definitely Programs for 3D AOI are prepared really faster. Having defined component database, programming takes no more than a couple of hours. Fine tuning takes u

That's incorrect. 3D aoi is extremely useful for determining solder flow and slope which a 2D can't do. Yes it's also great for coplanarity, tomb stoning, head and pillow and a multitude of other defects. Most 3d AOI use cad models and height measure

We have these standard pitch QFPs, for which we found some coplanarity error issues. The issues surfaced during BLT. We do not have any instrument to measure the coplanarity error before the component is loaded on the placement machines. Is there any

Dear Abhishek, I too got the opportunity to investigate this defect Lift lead for SOT. Lead lift in IC, and SOT can occur due to various reasons. Here are some possible reasons for lead lift and ways to avoid them: During the assembly process, mecha
