Pretty labor intensive operation as has already been mentioned. Bang for your buck is about zilch unless you're dropping expensive stuff at alarming rates. If you're not doing it already I'd start logging missed picks/drops/rejections and figure out

Not unless it's a case of "the only difference is..." What I mean by that is more than once I've been told the only difference in a new rev is one component or one change. But the truth was that was the only reason for the change, and in fact there

CL pretty much hit the nail on the head. But also remember that solder paste will not go "bad" if not kept cool. It is not a fruit or perishable item (sorry guys, it's not). It's just metal and flux. The only reason they want you to keep it cool

Hi Stephen, Q2) As per my understanding, no solder paste supplier or any organisation provide Mixing standard or ratio as it is not recommanded. However, I do know that some company, they allow mixing of old and new solder paste (as solder paste is

Well, I do know that different solder pastes have different lives. Sh@t, some solder pastes change characteristics from lot to lot. That's why we always restest solder pastes from different lots when doing an evaluation. Some of it has to do with

I believe you are describing a pin in paste process. Not sure where a stencil is involved. Depending on you machine/pump, you can do damage to it by running paste thru it. Paste is a metal and will wear out internal parts. Also, most pastes used

Turning off the grid-lok is not an option. I have used the hand inserted tooling in the past..It takes too long to set up and it does not accomodate warped boards. So I am I safe in saying that there is not much I can do aside from change my board d

I would appreciate any pointers to smaller machines that are newer and more flexible (vision, mostly). I am a one-man manufacturer, and have been doing all boards by hand so far. So, my budget on this is pretty small, but I understand that getting

"Unfortunately breakaways aren't an option - they are large boards and we already have problems hand placing components and probing them." Not sure what this means in this context....if you frame the perimeter with a 1/2" border on a V-score, how do
