Our company is beginning to delve into some 20 mil applications and I'm curious to hear what kind of success others have had placing these components. What kind of fall out rates we might expect or any specific difficulties encountered and what acti

Can Fuji machines such as IP1 and IP2 utilise 2mm pitch feeders provided by Hover-Davis? Has anyone used them on an IP1 or IP2, and if so were they effecient? Does anyone have 2mm pitch feeders that utilise an Fuji IP1/IP2, for sale? We are currently

We like to use "enameled wire" that can be stripped by hot solder. Formvar [105�C] will not do that. Formvar was designed to with stand the hot oil seen in transformers. So, it requires either chemical or mechanical stripping. Most polyurethanes

Hi Tim, 8-mil huh? Boy, that's getting down there...you know, placing 8-mil is one thing, but printing solder paste on 8-mil pitch is another. Most of the time when I've seen 8-mil pitch on a board it's been attached with hot-bar...but I guess

Square apertures can have a larger area within the same space than a round aperture. You can buy IPC 7525 from IPC. The theory you are missing has to do with: * Aspect ratio * Area ratio Search the fine SMTnet Archives for background on these rati

Does anyone have an older DEK 260? I was wondering if a 1995 model 260 with DeKAlign 2 is capable of printing 12 mil fine pitch reliably. (Assuming that it is in good working order) Thanks for any input!!

when you talk about stencil design, what would you recommend for aperture size on fine pitch if the customer insists on hasl finish on fine pitch devices? i usually use a 10% reduction on everything we have been using ( 16mil pitch and upwards and 0

Are you using "on-contact" printing? (is the stencil touching the PCB during squeegee travel)

What paste are you using?
