I would really suggest staying away from novastar on their ovens- we had a really bad experience with two of their ovens being unable to maintain temperature properly. We ended up buying a used BTU VIP70 and it has been working out great. A Heller 18

We had a gf12 and a 1200. I'm not sure what year they were. Sold them and got an oven with some horsepower. Our Novastar 8" wave solder machine still works well and is the reason we tried their ovens, but they just did't work out well for us.

I only have experience with universal gsm machines; they are cheap and easy to run/maintain, and can place just about anything we use. We do 0603 smallest for our products but I think it could do 0402. They aren't the fastest and are dated, but for r

I also am a huge fan of Universal Machines for their reliability, capability and dependability. Very highly engineered machines. Only machine I hear better than them is Fuji. Apple and Motorola used Universal's extensively so it tells you how re

Opal Xii if it has the 8 head conversion. Much faster in real life than a 2060, and parts such as cards more readily available. Had both machines and much prefer the Yamaha built Assembleon badged machines. Both will do 01005. If you do go Juki th

Gotcha. Yeah, it has 8 heads. I think I'm going to go with it, seems like people like it more than the 2060. The package I'm getting comes with the following feeders: -15 CL8x2's -40 CL8x4's -8 12MM -4 24MM -2 Tray Holders

Charliem, Thank you for the input. Following this logic, in case if there are no soldering issues, pad coverage and voiding levels are within acceptable limits and a gap between BTC and pad let us say 200um, this could be accepted, right? IPC-A-61

200uM seems high. I say this because typically our solder stencils in this application are between 80uM and 100uM thick which would leave the component height less than that after reflow. However if your not experiencing any shorting between pads I w

Hi All Respected Engineers, Now a days am testing a high speed 20 layer PCB but currently the issue am facing that most of signals give KOhm or Mohm resistance with respect to GROUND as it should be infinity.We have around 7 GND planes in our PCB s

I am having the same problem with the MPM Accela solder paste printer machine. If the fiducials are adjusted for PCB alignment, the location of the paste is then wrong, and vision inspection fails. This is a problem for both pad preview inspection
