Fuji Pick and Place Machines

Electronics Forum | Sat May 08 09:59:21 EDT 2004 | fastek

What you need to remember is Fuji didn't make a name for itself by building this XP platform. They're strengths are/were in their chipshooters. Don't just assume that because it's Fuji it won't have reliabilty issues. I'm not sold on this platform ye

Recomendations? Fuji CP7 or Univ HSP4797?

Sam- It all depends on what and how many boards you're trying to build that will determine if gantry or turret is the way to go. I like gantry machines and have been impressed by their increased performances over the last few years but they still hav

Hi Pete, Thanks for taking the time to respond. My experiences with Mydata would differ from yours, but as in life, different machines are for different circumstances. We have many low volume customers that love them - they are easy to use, upgr

How to qualify move from water wash SMT process to No clean?

Electronics Forum | Thu Jun 24 20:28:58 EDT 2004 | needhelp

We design PCBAs. Our CM assembles the boards for us. So far we have used waterwash SMT process to build the boards. Accidentally, due to documentation errors, we suddenly have a huge batch of boards built with No-Clean process. Although the boards pa

I wonder what that would look like? BUILD DCOUMENTATION Paste: OA XYZ-123 SOLDER PASTE. Note: Place refridgerated paste tube in Goldstar Microwave (3rd from the end of the break-room). Press "defrost" "forzen dinner". Do not defrost solder paste

We have definitely seen money saved. There is a lot less rework after reflow. Money is also saved in overtime. for example...when we are building a first article board with many placements, it is not always possible to get the first board through the

Efficiency Rate...

What are you measuring? Actual placement speed vs. rated speed? Machine down time? A lot of this depends on your type of enviroment. If you build high mix/low quantity/prototype your numbers will be very low and will vary depending on the complex

Now see Dave, now I have some good info on why it is "bad", This must be the lead enrichment I have heard about but never got any substantiated data or explanantion. I wonder how much weaker or less reliable these are. Is there any data that you k

Hi Simon, thanks for answering so fast. Well, our company is building several different products to monitor turbine activities (power generation and propulsion). So our boards are equipped with mixed technologies including minimelfs, 0402 chip resis

Industry time standards

Electronics Forum | Fri Sep 17 19:27:50 EDT 2004 | debh

Are industry time standards based on actual time...or money? From a start to stop time on a multi-machine SMT line our time is well below standard. (Our company uses industry standard (I'm told) based on .09 sec. per placement.) However each pick an
