I don't think it is a good idea to run your own board in house. The cost will be higher than let the contract out company do it for you. If you are looking for a Smt line.. You must spend atleast $400.000 for an use equipment. Printer= $100.000 Pick

I am totally agree with Gregp. This is the post when Mr. Clinton still a President and before the market slum. i just want to say because brian mention $$$400K for an SMT line as of the market now. If you spent 400K for just one SMT line at this ti

Hi Mike,I thing the most important question is what's the series of your production? Is necessary to buy a huge line or you need middle or even low class machine? The costs are very different. If we're talking about 1-2 million cmps/month you can get

Ron, The simplest way to process fexible PCB's that I have found is to use a process carrier fixture. There are companies that manufacture process carriers that are capable of holding flex through stencil, placement and reflow. The carriers are capab

Ron: Chris is correct that there is a bunch of fixture fabricators that make good products that will serve your purpose. Other fixture fabricators can be found in the archives. Problems with these fixtures are: 1 Out-rageously expensive 2 Very lo

We are a small start up. We will be buying a stenciling machine and semi automated pick and place. ( We have the oven) We are presently stenciling without any assit and loading leadless parts only(no fine pitch) by hand. We need to improve thrupu

bill is right about finding a reputable dealer, i do have a horror story about buying a machine that was not what it was sold to be. But there are some good ones out there.. if you do have interest in a machine feel free to ask the forum our opinion

Henry, TNT makes some good points. I have also found that the use of a 2% silver solder paste (provided that it's allowable) can help reduce the occurance. You may want to run a thermal profile on the PCB is question. Is the board thermaly equalized

Hi Henry, amoung all things that cause this funny effect the most effective measures in my experience were good PCB design (pads and equal thermal conditions for both sides of the components), placement accuracy and profiling, profiling, profiling. L

All of the information so far has been great, I would like to add one more thing to the puzzle. We have utilized a "homeplate" aperture on the stencil when the pad geometry or PCB design prohibits all of the above mentioned remedies. The hompeplat
