We don't build anything with BGA yet so don't have this standard but IPC-7095B, Design and Assembly Process Implementation for BGAs would be a good place to start. I don't know for a fact that it contains info. that applies specifically to your iss

I have been using Graphicode's GCpowerplace for years and have found it very easy to use. We are a contract manufacturer and I haven't yet run across gerber's that GCpowerplace couldn't read. The centroid extraction is very good and allows you to eas

We are also using Vapor phase for our process. We currently have 6 profiles that we have established. 3 for Leaded and 3 for Leadfree. We have set-up our profiles depending on the mass of the board. We do have some tombstoning depending on several va

We have used good industrial dish washers in the past. We washed very dense SMT boards with mulitiple BGA's. they always passed Ionic tests. You can buy these for as little as $500. The less expensive ones won't hold up to 140F water and suponifier b

thanks for the post... but are you sure that the type of mask i mentioned is photoimageable and as i understood can be removed from desired places (pads/soldering areas) using uv and developer (which i don't know what material is it). and also the

The normal price for new printer like DEK ELA is about US$ 45K TO 55K Depending on the dealer. MPM would be higher. China made printer is much cheaper and quality is almost the same as well known maker. If you want second hand I would suggest MPM

I would probably go with the Assembleon. It is a very well built machine with good software. I don't know Ipulse, but I've worked on the other 2. The newer cheaper machines could have problems. With potential down time, the difference could pay f

Hello Mark, I would recommend to look again on the pads. in many cases board design is causing these issues. Check 1. Is pad size good for the part 2. Are both pads the same size 3. traces connected to the pads should be same size 4. vias connecte

I do not know if you want selective wave soldering or selective point soldering? If you have good budget say, less than US$200k Vitronics is best for wave selective soldering. However, if you have low budget say less than US$100K I suggest ACE or K
