Hi SMT Frog We are using an upgraded Mydata TP9-1 system to place 0402s. We do an electrical test plus mechanical centering and use the C14 tool. A few things we have observed/learned: 1) Is the machine not picking the part up out of the tape? Po

Hmm, that's a fairly old machine, even older than mine! (I have a CSM84 PA130640). Anyway, it is best to program the machine from CAD system data, I wrote a little program in C to read in the component type and XYR position, and produce the file in

You should ask yourself a bunch of questions before you consider going down this path. The first being where are the bottlenecks in your existing line and is there anything you can do to eliminate or decrease there bottleneckness (made up word). I

I'd recommend not using them, personally :) The long term reliability of the SMT joint is suspect, IMHO. I had them for an in-house manufactured bed-of-nails test fixture for testing somewhere north of 5000 units....after the first 100, we were rep

Hello M. We are a low volume high mix manufacturer with a total of 7 Mirtec AOI machines including a new MV-6 OMNI 3D system. I am very pleased with this machine! When we did our 3D AOI research, my team narrowed the field down to 2 vendors, Mirt

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce

Does anyone have any ideas on setting up a parts library/database on an SMT line? We would like to identify a particular part by it's package style, instead of by the customer's part number, in order to reduce the amount of entries in the library.

Rob: Someone's out there turning over stones, eh? Roller Tinning, Rolled Solder. In printed circuit fabrication, a surface coating of tin-lead, typically 1-2 microns thick, applied to preserve solderability. Still available from some fabricators

Ok so for me, spray fluxing is the way to go every time....for one you don't need to worry about colapsing your foam with pallet's that are hot or worrying about your pummace, your thinners, SG and so forth...man life in foam fluxer land was hard. N

Dave: In terms of heat transfer, air is 78% nitrogen, and the remainder is mostly (20.9%) oxygen (roughly the same molecular weight as nitrogen), with a bit of argon (0.9%), CO2, hydrogen, monosodium glutamate etc. So you would expect virtually no d
