Hi, We are looking for some measuring machines to evaluate the ability of a SMT placement machine to produce quality. We will mount some dummy components on a glass plate and then insert the assembly into the measuring system which can measure the

Daniel, If you just plan on mounting chip components don't worry about getting an accurate measurement. The parts will vary in size, corrupting your accuracy measurements. If you are going to place leaded components you can probably get awa

I posted a similar question a few months ago. Basically, I asked: "Can anyone who is NOT a salesman for an OI company, provide an objective argument for purchasing these very expensive systems." Well folks, not surprisingly, no one has posted a respo
