DaveF- did you get your answer? By the way, did you ever find that misplaced drill or did you have a fine time at Wal-Mart, grumbling in the aisles whilst evaluating a new do-hickey replacement? I believe I have read from the responses that most agr

Back in the days when pots, skillets, etc. were made of cast iron, vegetable oils were used to "season" the iron to prevent rusting and also from the food sticking to the pot during cooking. It would be reasonable to believe that you could use the sa

So, what is a �Contaval Pallet�? And who, my I ask, came-up with the cockamamie idea of retrofiting of the edge hold conveyor? Last time I checked, everything was fine, all profiles were working, etc., etc. Just think, if you move the fixed rail i

While we have nowhere near the volume you do we have bent 2 A-14s in 3 years. One was definitely operator error in that a tape holder arm was left floating the other is unknown as this particular (ex)operator wouldn't admit to knowing the time of da

The point behind traces and vias on my test is that I don't only want to perform test on printing and placement but on reflow too, so a board with many components and no trace will not react like a board with traces on it. Unless you or someone else

Thank you all very much for the responses. The solder is eutectic and the problem, as far as I can tell, has been around before I was here, 2+ years. The flow machine is a treiber with 2 bottom preheaters and 1 top. The solder pot temp is 500F +/-4F

Hi Armin Printing equipment can be divided into two main groups; In-line and off-line. For "small" production sites an off-line screen printer should be adequate but for high out-put placement lines, where the product cycle-time is short, an in-line

Since yer talkin� $$$$, non-quantitative measure do not apply. I understand someone told you to do payback. But, we don�t use payback for multiyear projects. Regardless, the analysis is similar. For each machine, set-up a multiyear spreadsheet li

Hi Nightbull, I'm with Dave. Don't see the need. Good stencil, good operator, reasonable machine with at least manual vision alignment, good set up, solder paste that satisfies you and the customer, regular maintenance, and how can you go wrong? As

We would benchmark our times with the most experienced operator and them boost the time by 1/3. Example: If it takes Mary 3sec to insert the component, 3 secs to clinch and cut the leads (it is not advised to cut the leads after soldering), and 8 sec
