| Dew: | Is this the third or forth software alignment for Fuji? Hope they stick with Unicam for a period of time... | Just my two cents.... I believe it's the forth, MCS OS/9, MCXE,F4G, and now fujicam...were there any others I missed? Personally I

Bernard Interesting point. Please help us better understand: * Why do 'VIA hole, PTH hole sizes may need to be changed', aside from the obvious with hole-to-lead clearance? * What should the designer 're-evalaute the board before changing'? * What

Thanks Bernard. On your profile: Adding gold to your solder alloy will increase the liquious temperature. So slowing your reflow oven conveyor is a perfectly reasonable approach, especially for pads with low surface area. We don't even notice a di

-If the aperture volume is the same, there will be more solder on the HASL finish joint due to the solder already present on the pad. This difference is not usually enough to cause insufficiant solder volume but will "look different". Sometimes an

Cartridges/dispenser systems supply even paste volume to the screen. This will help provide the most consistent squeegee roll as well as paste deposition on PCB. Messier, though = much printer maintenance. Some people also like to use a caulking g

Mydata machines are very solid. They are always upgradable since the base machine is essentially the same. Recent advancements in camera and feeders have increase placement speed. However, this is generally not the machine you would select and expect

Stick with what you and your production people already know...........Fuji. Between new and used Fuji equipment on the market, you can do a lot better and with a lot less money than you think as opposed to new Mydata or UIC. You will be compromisin

All, I have hix mix and medium to low volume. Alot of the orders are the same monthly by quantity and product. I have gone through and optimized as much as I can. I have orders to justify equipment as well. I want to accomplish more output of product

Well, you have Fuji's now, that's a good argument to stay with them. Your maint. guys will like it too. Plus, depending on size of MyData, you may have to really re-adjust your line(s) to fit em'. I'm not bad mouthing MyData, I think they are gr

What kind of changes could be expected by changing from a HASL finish to gold? We have a board the had been being coated with HASL but was changed to gold to make priting easier. Now, even though the soldering looks fine, we are getting fallouts at G
