The process is not that difficult so have a go as soon as possible. Take a board wipe some paste on a board stick the part in and run it through the reflow process. Don�t worry about balling just see what you get first, that what I did first ! The m

I think the main purpose of cleaning a fiducial is not to make them nice and shine, but to get a haze on them. In particular dome shaped fiducials create too much reflection from the light source and distort the image. The eraser pencil is a bandage,

We have this problem with our High Temp. solder lines. Tombstoning is actually the term used in our facility. We found that the component termination width was a main contributor also profile ramp rates. Visual inspection will catch most of these rej

Hi! I have problems with the SMD boards during wave soldering. Mainly between the pins of the SOICs there are small solder balls. Maybe somebody had the same problem and could solve it. Please give me some ideas what causes this problem and how it

Same problem for me. I'm a registered user, but when I fill out the "login" box, I get back to the main page as nothing had happened. And of course, not even the link to the e-mail section. I had problems like that in the past, due to not accepting c

My company is in the process of determining whether to setup an in-house SMT line. We presently do thru hole assembly and subcontract SMT boards which are growing in number. The economics are not my main concern now. The intangibles, i.e., control, l

I am currently having trouble writting a PD for the part that is layed out in the link below. I am placing this part with a CP4-2 with SMD3 vision. I think my main problem is with the Vision #, but if you would please take a look at the link below,

Hi, I'm looking for vendors that manufacture connector pins that would solder onto the edge of a small SMD pcb so that I can mount it as a SIP onto a larger PCB. Better yet, are there small diameter pins that can be soldered into thru-holes so the SM
