Hi, The thing with Formula 1 is that they can afford to throw innumerable bodies at tasks (i.e. 8 people to change 4 tyres, 1 to hold a jack, 1 or 2 to refuel, 1 to hold a stop sign, 1 to hold a fire extinguisher, 1 with a stop watch, and the bloke

There is no set formula. You need to customize this number around your operation. Depending on how you account for: Capital Equipment Costs Utilities Building Costs Overhead services Consumables ( Flux, Paste, Glue, ...... ) Once you get the costs

There is a formula for that out there somewhere. It has to do with the part mass and the area of solderable surface. If the part mass is too great in relation to solderable surface area, the part falls off in a d/s reflow cycle. Anyone remember th

Our programs are created in an ASCII format ( we do not have Unicam or Circuit cam )So using Microsoft Excel,we open/load the finished PNP program and then we sort it by reference designator. Still in Excel, we then open/load the BOM (in an ASCII)

Yes it is used for PCB, I have used it in the Automotive Service Industry for many uses. Most popular as a Brake assembly cleaning agent. It is popular today due to its low FLASH POINT, unlike other solvents that contain Heptane, Xylene etc thease ha

You can use any metric ruler to do that. Examples: Pitch 2mm x 200parts = 400mm length or Pitch 4mm x 100parts = 400mm length You can also calculate approximately how many parts you have on the tape by using formula. I don't have the formula but

Is the company near to you, if so walk up to the back door, with a load of cash in hand and a suitable container. Another option get your hands on their formula and have it made up by a chemical batching company. If you can't do that get the MSDS and

Wolfgang: I agree that the IPC pads are reflow / top side wave solder. We run bottom-side PCLL at 45� to the wave with fairly involved solder thieves. Ta. Dave F
