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

Now that's an approach I've never thought of, inspecting a different portion of each board (I'm assuming that you program a few different patterns and run them sequencially, or something like that). I know our stencil printers don't provide that opti

Hi, Can anyone advise what would be the possible cause of having the same short problem at the same spot even after 3 time rework, with a brandnew BGA. I have rework boards with BGA shorts. The problem is most of the shorts boards, will passed afte

Zam_bri: If it were a mystery .... there can�t be any answers . Possible causes: - Short is in the PCB ( not very propable, cause you�ve checked that ) - Short is in the BGA ( not very propable, cause you�ve checked that ) - Short occurs due to so

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

All the response is appreciated. We have 4 SS machines and 2 operators (normally). Some jobs take up to 15 minutes (multiple boards), some take less than 2 minutes (machine time). Some involve fixtures, preheat, some may require the operator to mon

Is the process the same for every product running through the selective solder machine? Load program, acquire or set up fixture, Change/load flux?, Change/Load solder pot? Are the machines cold when the operators need to use them or are the machin

Recently on one of my assemblies(sn/pb) I started seeing leaded BGA failure at functinal test for opens, but when I inspected them through 5DX and ERSA Scope it doesnt seem like there is any opens or insufficient and half no. of boards passed functio

We run a MY12 and our largest layout has 9700 components of which about 8500 (88%) are placed by the Hydra head. Average run time for our layout is 75 minutes. Based on that and depending on what percentage of your components are Hydra mountable, y

Hi Jorge, The success of such production purely depends on process control. One needs to first understand the board layout in detail, and evaluate any critical components for their temperature handling capabilities. Remember, you are dealing with com
