I like what you're doing. 20 years ago anyone, hobbyists and tiny garage-shop companies could create electronics devices just as sophisticated and cool as big corporations. Today, SMT has largely trashed the creativity (and competition) that existe

My suggestion is to conduct a Design For Manufacturing (DFM)study on the assembly in question. Pay particular attention to the pad sizes, component lead dimensions and satisfy yourself that those two factors are correct. Given that pads match compone

Hi Dback, Yes, i'm open "dog bone" aperture for my chip component. this is to prevent solder ball issue. For fine pitch i'm opening square with full length and half width to prevent bridging. Btw, if "dog bone" is not for chip component, what is your

Shy, You mentioned that you are using "dog bone" apertures for your chip components? It doesn't make sense to me. I thought that the "dog bone" was used for fine pitch devices, to keep the solder away from the center and avoid bridging. It doesn't

Hi Dhanashekar, I'm with Chris on this one, unless you are carrying out 0201 or ultra fine pitch placement it's a helpful but not critical tool. We found most print errors were avoided using the 2D vision on the printer, combined with plenty of aut

Dear all, Is there anyone who has the experience in conducting Push&Pull test for fine pitch components?i.e.SOIC,QFP. The customer clearly stated that,"every lead should be tested for selected components".but, you know that,the fine pitch,0.5 or
