We have been in contact with HK Yush out of Shen Zhen that is marketing an SMT metal laser cutting machine similar to the LPKF 6060 series (IA Tech SC-6060). Apparently there are no customers in the US. Does anyone in SE Asia have experience with th

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

you can try Guillotine type PCB Depaneling machine, with very low cut stress , won't hurt components , the cut blade thickness can be make to 0.7mm . http://www.sam-smt.com/pid11368146/PCB-depaneling-Machine.htm

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

Hi Phil, Tabs every time for me, but running in volume so the slow down in tool travel for cutting important. Have used Cencorp 1000 & 1300BR, and Asys ADS01 - both in line systems with grippers from the top to hold the board and the router underne

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

It is not as easy as just buying a Laser machine. There is much more involved in bringing this in house. With the price of stencils these days, you would have to be consuming a very large amount of stencils to justify such an investment. Steve is r

Thanks everybody for your comments. I am not going to move to stencil waterjet cut. But because recently talk to people who want to move in that way, so that's why I am trying to get infos as much as it possible in order to learn what does it mean a
