Yes, your observation is accurate. Different process steps have different inspection requirements which necessitates employing different imaging technology to ensure the best performance (detection and throughput). Orbotech, for example, offers both

| DO you know of an Industry Standard that describes solder paste geometries requirements? | If it were only so! Most people I work with, because of so many variables concerning solder paste, its composition, particle size and shape, and application

Quick Change Tooling is one advantage for DEK when comparing the MPM UP2000. DEK has Form Flex. Good system, but I've heard concerns about long term dependabilty. All support tooling options offered on the UP2000 takes a bit of time to set up. So, If

There is so much confusion about this cognex not reconized statement, and it's time to step in. The box on the out side is a cognex 2000 system. The reason for the cognex not reconized statement is very simple. MPM wrote the 4.1y software looking

Start with your board first. Do you have resist/mask between the fine pitch? Is the finish HASL or a flat surface? If there is no mask/resist between the fine pitch leads you may want to reduce the apertures 5%. If the board is HASL, that means yo

You need to perform process a capability study prior to putting these controls into place. Cleaning a stencil after each pass will get ugly, solvent residues remaining in apertures etc. 2D inspection is good. Change paste every hour will get very

Hi All, I've been told that 3D AOI machines are a solution to the false calls that you get on a 2D machine, but I don't really see how the depth information can help in eliminating false calls for unreadable markings, misregistered parts etc. For s

2D SPI? Depending on the focusing height PTH inspection, or PTH solder joint inspection? Strip down if it has a granite slab in and turn into an engineering table for manufactured parts inspection? Stick a router head on it if you are really bored

I would also "nice to have" because of your process. Inspecting solder paste from a 2D point of view manually would not assure you quality if the paste is 75% off pad. Plus hand placing onto solder paste causes it's own set of problems which will c
