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

Mark, This is a big topic. Where are you located, it would probably be best to hook you up with someone in your area. Anyhow, lead or lead free should be based on whether the circuits are lead or lead free. I would guess that cell phones would all

It probably depends on the Silver content. We are also using Sn62Pb36Ag2. The paste manufacturer told us that the reason for the small silver content was so that it could wet better to the lead-free component and board finishes bearing silver.

Hi all, Sorry for the late reply..I am sure it is flux residue..Found no such symptom as Grey mention above. This is non clean process and no way we can clean this whole big board(Server) with any kind of flux removal...Currently, the ICT probe pre

It makes sense if you think about it. Siemens was a dead company ready to fold up their tents back in the 80's and early 90's. To their credit they stuck to their platform...got somewhat lucky and the market sort of came to them as the wave of users

SMTNetters, I have a product coming down the pipeline that we'd like to make pure double sided reflow, it'll be RoHS product, and the hope is... we'll be able to solder the thru-hole stuff by screen printing solder paste and reflow soldering. Anybo

I need advices as to how a gap between the bottom of an LED (1209-package) and the PCB can be controlled on a small rigid-flex PCBA? The problem that we experience is due to tight tolerance in the design of our molded housing in which this PCBA is as

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

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

Good tidings, all. I am looking for a machine that will allow us to mount a flat flexible strip (such as TennRich's B.Type) to a row of pads on a PCB. I have not much knowledge about the process, I guess I expect to see a machine with some hot bar.
