For solder joint inspection you cannot beat AXI. That's what is was designed for. AOI machines were designed for component inspections and solder joint checking was an add-on. In transmission AXI you can get a measurement of the whole solder joint. A

Sorry, I have not read the article. However, I do have five years experience constantly tweaking an AOI system that ran ONE product! The strength of the machine was solder inspection. The biggest problem was component color variation and shadowing

For Automated x-ray inpsection system comes in 2D and 3D. 2D also know as the transmission xray inspection where xray are generated from a fixed point source. On double side board, this does not work that well. That where 3D Automated x-ray inpsectio

Hi Refering to the Apr edition of SMT , page 24 to 29, anyone got experience on implementing the AOI or 3D x ray : a) What is the pros and cons? b) What is the trend in the PCBA industry for wave soldering inspection? c) Will this implementation co

Jason, In Transmission AXI the entire solder joint volume is imaged, not just a slice (no missing information) as with Cross-Section. Also, there is no signal loss from mechanical or digital image reconstruction (highest contrast and edge strength).

Did you solve this issue? It doesn't much look like the flux dried out, ti should be across whole board and has much more same defect if flux dried out. Did you have failure ratio data to show the defect location, for example 10% at location A on bo

if use more aggressive paste,be careful risk of electro-chemical migration

True, but with rosin it should protect the joints pretty well right?

Hmm OK. Even a NASA article describes that rosin is safe not being cleaned lol.

Over the years I have gotten the best support from Aim and Alpha and the least support from Kester. If you can, you might want to switch to a solder supplier that gives good support.
