Apart from recommending a placement machine since I don�t know you product, part mix or tact time; I would just like to point out a few other things to consider when choosing a different placement machine. Feeders are a big thing. Mydatas are good

We expect to see a copper shadow along the edge of pads when soldering boards with organic solderability protection [OSP]. IPC-A-610 has defined this as acceptable for years. During early reflow stages, the flux in paste dissolves the OSP where ther

If you are using a well maintained chip shooter, you should not see more than 1%-2%, and that is on the high side. Most pick and place machines (depending on what they utilize) with laser, vision, mechanical centering will most likely reject a diffe

We issue extra parts like this: 8/2 caps and resis. - 40 over 8/4 caps and resis. - 20 over 8/4 IC's - 7 over 12mm - 7 over larger feeders + stick + matrix = the correct # req'd. These #'s were based on our first SMT lines (used equip.) and we made

We used to use the Tapesplicer tool available from http://www.tapesplice.com (Sierra Electronics), in a high mix, low volume environment with MyData's (older feeders). Short review: It worked. Longer review: First, technique is everything. Splicin

My opinion to hold on to your machines was based on the current market situation. First of all, I don�t believe that a customer with ten boards will go to China for prototype production. Truth is, that the remaining market here is the prototyping mar
