We use it almost exclusively in manual mode for PCBA failure analysis. Our main purpose is to find head-in-pillow defects; secondarily incomplete wetting of ball to substrate. In two years of almost continuous use we have only had occasion to use t

Hello all. I need you advice and opinion on my problem with BGA drop off from the boards. Initial defect was ICT fail, but due to some accident, the board fell off, and the BGA just pop out. After some search, I end up to conclude it is a black pad

The closer your inspection the more defects you will find, the more rework you do the possible cost you will add and the potential increase of damage you could do to your products if rework is not up to a machine copyable standard. "Is there any in

I can only speak for Mirtec and Yestech AOI for SMT Solder Inspection. We do use Koh-Young AOI for Solder Paste Inspection. As usual ,you need to identify exactly what it is you are trying to achieve with your AOI, if you are just trying to fill a

Hello, there are several great machines you can choose from. I would recommend making a benchmark, if you can. You chose 4 machines that meet you requirements (mostly prize range) and make them program and debug one of your products. After that insp

What type of flux is in your solder paste? Active or No-Clean? With lead free solder you really should be using an active flux. The lead free oxidizes during reflow if you are not using a Nitrogen or Vapor Phase reflow. So a more robust and activ

Hi all, I'm having some troubles while trying to set up a wave soldering machine that was working just fine until a few weeks ago. The wave soldering machine is quite basic chinese made. It's 2 meters long, has spray fluxing and a short preheating

I would cut a piece of cardboard to the same dimensions as your circuit card. Run that through the fluxer of your machine and pull it out before the pre-heater. Take a look at the cardboard and verify that flux has been sprayed on it. That board look

First profilers are expensive and you can use temperature dots for setting up a wave. You stick them to the top side of the board and they change color based on temp. Top side temp should be around 250f or 125c when it hits the fountain. If you spra
