90 Knoop. Q2: Thickness is 4 to 10 u" for Au and 300 to 400 u" for nickel A2: This looks like a ENIG spec. Although, the Ni is quite heavy, 150 uin is sufficient for most applications. [IPC-4552 ENIG specification: * Gold thickness of 0.075 - 0.125

I have been using my topaz X for about 4 years now and I feel that I am fairly knowledgeable about it, at least the functions of it that I use... I am trying to use the LCS to place some qfp chips on a new product and I have set the whole thing up t

If memory serves me right, if you are test picking a component which will be served to the machine via an LCS the 'pick position' will automatically set itself to feeder slot 1. If you change this to something more central (I used to use location 4

Ahh, yes. Just about the same time you replied someone else I asked said the same thing! I didn't realize that you had to put the part on by hand for the vision test. In the book it says to leave the feeder position set to the default setting. Fu

Hello Bob, we changed the nozzle z parameter until we got limit errors and backed up 1 mil. There was a slight reduction in the limit errors on the pickup of the component but it is still a problem. With the mod code we adjust the soft z height to ab

If its a tall part and you are trying to scan it lower than 200 or so...you can have this problem (limit error). Thinking of things to look at.....Is your z-rod spring sticking? Push up on it and it should spring back with NO hesitation...if it does.

We have been having a recurring error on one of our Quad 4Cs. When it picks up the first of 8 47uF SMT capacitor it stops with a limit error. If we do 2 consecutive function 30s, the problem goes away until the next board. The first function 30 re

The joint IPC/JEDEC standard currently specifies a limit of one bake cycle, regardless of the temprature or duration. In the proposed revision this will be replaced by a maximum cumulative duration of 48 hours at 125C. The reason identified for thi

Can't help you with the manual but do have some tips: If it was shipped, it's possible someone tied axis or blocked stuff for shipping. Look for that. Look for bent sensor flags + go into I/O and check to see all sensors you can find are working.
