Snaggletooth, I spent a good portion of my career fighting solder shorts on BGA's and QFP's, tombstones on 0402's, solderballs on passives, etc.. I've solved just about all those issues, and didn't solely rely on my stencil manufacturer... Your ste

Good day, You are right. PanaPro system isn�t very easy to use; it�s rather complex system, but very flexible and very powerful. It has a powerful core together with a lot of useful software functions. For example build-in text post-processor, good

I struggled with the std too, when trying to justify the need for a desiccant cabinet. according to my interpretation: 1. the components are baked at 125 or 150 dec C within 24 hrs of manufacture (this is MET) and sealed in the MBBs at the component

We design a broad range of DC/DC power supplies for various telecom, internet, and computor applications and have been succesfully using intrusive reflow for ~7 years now. Our pcbs range from 0.065 to 0.090 in thickness and are moslty dense 4 to 8 la

Hi Craig: I agree with muse. The problems almost always will show up later on duringg life cycles in terms of reliability problems. While the solder joints may look acceptable right after production there is no guarantee of meeting the reliability r

We have a Siemens S15 and an F3, which we have only had now for about 4 months. We have an old line of HS180s and an SP120 and have found that the S15 and F3 do not have the option to skip a part if one runs out during placement. We from time to time

Efren, Most of the previous posts offer valuable information. Certainly you should consider panelization of the individual circuits. Otherwise you'll waste valuable production time passing 3" boards along the line. Your orig estimate of min thruput

Dear All, We plan to setup an assembly line for our small volume production of PCBs (about couple hundred PCBs per week). The board has about 150 components (less than 30 types) and a few BGA and IC (majority is SMT, only few THT connectors). We hav

I've done this stuff on UP3000's and AP's so hopefully my advice will help with your 2000... You can get into all upper level user modes, correct? You don't mention test, cal. or field service mode. If you can't get into those, I can send you a pr

Verify that the CEMs machines and processes are capable of assembling the technology of your boards- smallest components, largest components, finest pitch, flex circuits, etc� Are their core competences aligned with your requirements- assembly only,
