Josh From looking at your pix, we don't have a clue. [And we're going down to the nurse's station to get our eye checked because we don't black bubkus.] More than anything else the: * White on the pads could be solder * Copper-penny brown on the pad

Dave, I know that black pad isn't solderable by any alloy. But it's still justified to relate the nickel barrier plated boards to lead free. Before lead free the predominant board plating was HASL and OSP. These platings disappeared with the switch

Head 1 is not placing the parts in production. Same component is placed by head 2. Head 1 camera is camera 12 type and head 2 camera is type 8. Machine re-set done resent proper data and interchanged cameara still same problem was foundd in head 1.

We use Cooksons prepaid "Pot-Rite" program which sends you as many preaddressed envelopes and order sheets as you order. When it comes time to send out a sample you just pop it in the envelope and mail it out. They also have all the molds and ladles

If you're questioning their motivation for testing accurately, I'm sure they would *love* to sell you stuff to balance your alloy composition ratios or just replace all of your solder outright. IOW, I don't think you need to worry about them paddin

I am running Autoprogram ver. 5.31 and need to split a large program so that it can run on 2 seperate Quad 4C assemblers. When I generate the program I select the "Breakup Program for Seperate Central Controllers" box but I do not get 2 seperate prog

You are correct. There is an option under Generate Program to Breakup program For Separate Central controllers. I choose this option and then it asks for a suffix to add to the program name. I am using Head as the suffix. After program generation I s

Yep there are nozzles on both machines. This is a very quirky program. I remember when I first loaded it I couldn't get it to run. I reloaded several times, double checked all of the settings in the autoexec and config.sys files but couldn't get it

Oddly enough, I find it more often than not that the supply type is not mentioned in the data sheets. And if the original author was saying 0603 in a metric package, then it would be in 8x2 tape. Even in the US, some companies use the metric names
