0.4mm PCB Thickness - production issues

Electronics Forum | Thu Sep 14 19:19:38 EDT 2006 | SWAG

I would try to panelize as big as you can for sure as you'll spend more time handling single boards than running anything. Additionally, this size is very close to smallest capabilities on GSM depending on your configuration. Fids on all boards in

Run Fuji IP-1 at 100% speed?

Electronics Forum | Fri Sep 15 14:29:10 EDT 2006 | bvdb

Thanks "j". There is absolutely no support for Fuji in New Zealand or for the older IP-1 and MCS/2 programming computer. We got the machine working by studying the FIP-1 Operation Manual and the MCS/2 Programming manual and a lot of trial and error

Quad 4c Nozzle Height Saga

Electronics Forum | Tue Oct 10 11:06:04 EDT 2006 | lheiss

Hi All, I wasn't sure how this would turn out until I ran some production. As I suspected, after every nozzle change the machine dumps the first 3 pickups, checks the nozzle height again (function 30?) and then begins placing with correction with n

Mydata package libraries

Electronics Forum | Tue Oct 24 10:03:24 EDT 2006 | billyd

All - I'm hoping I can get a little feedback here on my package libraries for my Mydata machines. I have four tied to a server right now, and I have several operators that apparently like to make packages, so I have some called 0805-05-A-MY-9-2 and t

Cleaning Paste from 2nd Side Print

Electronics Forum | Thu Nov 02 18:56:10 EST 2006 | darby

John, As Dave says, never clean raw paste. Let it sit for at least 24 hrs if you can and use a plastic spatula to wipe off the bulk of it. The "drier" the paste the easier it is to remove without it travelling down vias etc. You will then have to cho

The Most Difficult BGA Rework EVER!!

Electronics Forum | Wed Nov 08 08:48:45 EST 2006 | markhoch

Okay, here's the deal-e-o....I need to find the Nation's Best BGA Rework Specialists. I have 50 PCBs each measuring about one square inch, that need to have a BGA Ring Socket Removed, eight capacitors removed, and a new ring socket installed. Sounds

Design rule for vias

Electronics Forum | Wed Dec 06 21:28:12 EST 2006 | davef

It's worse than just using the test equipment manufacturer guidelines. Along with that, you have to deal with each of the test fixture fabricators' preferences as well. What this boils down to is a negotiation with the test engineering group as to w

Gold fingers damage when plugged into connectors

Electronics Forum | Fri Dec 08 14:35:28 EST 2006 | glynnhamer

We currently are building a pcb that has gold fingers, about 36 in a concave V overall shape from .275 on the outside edge fingers tapering down to .197 in the middle of the 2 inch span that plugs into a shelf connector. These fingers are on both sid

VSSOP 0.4 mm Pitch pad design & Stencil aperture

Electronics Forum | Thu Dec 14 22:28:38 EST 2006 | Tony

Hi, where can I find info about how to make the pad design to work for VSSOP48 0.4 mm Pitch & TSSOP56 0.5 mm pitch components? I should also mention that we are working in a project that this 14 layers High-Frequency RoHS board is included. The pad c

Why not? If You think it has a bussiness case so go for it. We are currently using a firm that has 24h delivery time if neccesary (we need to order before 9'clock in the morning)and we once in a while use this for some prototypes. Their regular shipm
