Best way to fan-out 0.5mm pitch BGA for fastest prototyping

Electronics Forum | Wed Nov 23 19:50:23 EST 2016 | gmscribe

Hi guys, I'm working on a design involving a 223-pin BGA with 0.5mm pitch (ball size 0.3mm) with a 16-bit DDR3 controller involved. Currently routing a track between two balls is resulting in a track width of 0.1mm and a spacing of 0.077mm. Now the

4 Mil Pcb's/yr) My choice was not to go to one vendor for a solution but, to pick (In my Opinion) the best equip to each of the jobs in a SMT line. Hence I have multi-vendor High Volume lines. Back to the ? Budget constraints and cost per placement

Has anyone looked into Vacuum storage on moisture sensitive devi

After a few problems and time constraints on baking moisture sensitive devices, we are looking at solutions to storage rather than going after a rebaking solution. One thing that always bothered me about baking was the oxidation on the lead finish,

Hi Grant, If you're really looking for speed, I'm sure you're looking for another machine for doing the QFPs, BGAs stuff etc. In that even, why not have a look at the long proven Assembleon FCM machine!! It is a totally different concept with UNMATC

When does SMT inspection/touch-up become rework?

Electronics Forum | Tue Jan 25 21:29:24 EST 2011 | rway

I understand what you are asking. I just wanted to ask if you or your company has considered purchasing an AOI or ICT? Perhaps both? Both are valuable tools in the manufacturing process. We lived without our AOIs for quite some time, but in my ca

Have you verified the measurements on the bench with an LCR meter? Chances are you are experiencing aging with these ceramic caps. We have similar issues with X5R and X7R caps. You will see the effects of aging with returns from the field as well

BGA Pad with Irregular Pad size

Electronics Forum | Fri Sep 05 09:15:36 EDT 2014 | rgduval

Hi, Edri, It's not uncommon for PCB fab houses to change pad sizes like that, due to design constraints....however, it always aggravates me when they do it without checking with me first. In my mind, that's the first sign of potential bad issues wi

Inspection Machine Capability

Electronics Forum | Wed May 09 03:29:16 EDT 2001 | Eyal Duzy

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

Okay guys (and my fellow lady lurkers), I am trying to determine WHAT the segmentation is for the products in the pick and place industry. For example, I know in screen/stencil printing, there are manuals, there are semi-automatics, mid-
