How is the component marked. Is it ink marked, laser marked or what? What is the material that the marking on? What volume are you looking at? We used a small, pencil-sized sand blaster, loaded with bicarbonate of soda to errode the mark off of plast

I am supposed to heatsink a Temp sensor with leads .9-1.1mm(.035--43"). I have found on our engineering units that the smallest heat sink I have found commercially is still too heavy for the leads and unless the operators use exxxxtreme care the wei

Steve, I have just one question. Do you place any other QFP's that have 20mil pitch or less? Do you see the same problems? You might be able to solve the problem using other methods. If not, will the ENIG finish on the boards be a profitable move. I

It is apparent that you have evaporated the flux before you reflowed. You got lucky when the paste slumped and you didn't get major problems elsewhere. A more reliable solution is to adjust the stencil apertures for the part that is experiencing bri

Sounds like "place" problem doenit? As best as I can tell [ever notice how the trail get fuzzy pretty fast, when someone starts asking probing questions], we received someone caps manufactured by someone other than Rolm through a distributor. The p

Most places I've seen don't do anything special. But then again most places only have chip components on the bottom of their boards along with some thru-hole. The best way to find out if you are going to delaminate is to talk to the board manufactu

Greg: You might look for : - smallest board size - largest board size - finest pitch you are able to handle (safe) - Parts/hour - units/hour (If you find your bottleneck it will be easy to determine) - number and kind of feeders, components per line

Solder skips on SOT23 parts is the most common issue when soldering surface mount designs. The two most common causes are the wave height too low or there is too much gassing of the flux as it contacts and seperates the wave. Stck some parts on your

Matt, I assume you mean F4G. This comes as a complete packadge...worth the look, but.......... You might want to look at changing your PD naming convention. I can't imagine having so many new types of parts that you are being overwhelm

Matt, I suppose the automated system you refer to is the VPD-101 camera system that captures component image and with a few clicks on the mouse you are able to define all the element data and dimensions of that part. Check with your local Fuji agent,
