Hi ... We use DRS24C Air-Vac machines for placing BGA devices, and have been having problems with shorts on corners of one device in particular, its a PBGA and its size is 4.5cm square and 15grams weight. When the component is picked up and the com

Thanks for the reply Hege, I calibrate the machines every 3 months and have checked that the board carrier to nozzle parralelism is ok. Have tried many different profile settings using a MOLE for readings but still collapsing on one corner. I did

We use SRT. We still have machines that are over 5 years old and are functioning very well in the BGA, QFP and yes CSP area. The critical part is getting the right Air nozzle for the part size. Also the software has a auto-profile feature that wor

I am currently using the following equipment for low volume and occasional BGA rework: BGA-3591/CSP-3501 115V Rework System. This system is fairly inexpensive, unsure of the actual price, However, can be used to rework QFP and PLCC components.(of co

We are thinking of getting a small pcb assembly setup for a small manufacturing co-op here in Los Angeles. Our experience consist of manual soldering of through hole and smt components. A quick search suggests that there are a few turn key opt

We have both DRS24 and DRS25 here. I think you will be much happier with the DRS25 as the underboard heating is superior, of course after a year of using the 25, it has its caveats as well, though minimal. I was a little surprised that you are havin

It sounds more as though you have a profiling problem primarily, however, if your placement is not square to the board, then you should get your machine setup correct first. After that you can get to the profiling. If the BGA is brought up to tempe

Hello everyone, Can you please recommend a sensor to measure (contactless) level of solder inside of the wave soldering bath? ideally it should be a sensor that can reliably measure distanceto the melted solder and provide distance (as a codified si
