Hi, You don't need X-ray and all that crap. I would get an old MYDATA TP9 or something like that, and a manual stencil printer and a batch oven or a small inline oven. Should do the trick and be very low cost. Should be simple to use as well. Tha

Subtle spamvertising there. Lower Cost small machine brands worth looking at are probably: Mechatronic Intelligent Drives (UK only?) TWS Autotronik or their Manncorp branded models in the USA Fritsch Innotech Heeb (a virtually invisible market share

The QFP pitch is 0.5mm. Pad size is 1.475 x 0.3mm, and the new aperture size is 1.32 x 0.22mm. I'm not sure about whether or not it is lasered, but on the newly ordered stencil I selected the polishing option. Looks like the pad width is already 2/3

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

Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

The boards are expensive because they are your product... covered in circuitry. A 2% scrap rate costs twice as much as a 1% scrap rate. Say the parts on your consumer electronics board cost $5. A machine that makes 99% good boards and 1% bad boards

John, programming can be done easier, but you have to pay the price somewhere. I would recommend using the following sequence if you see a lot of new products all the time. 1. Use your own part number system. With these numbers you will fill up you

John, contemporary machines provide their own software for programming - most you can do completely offline. There are several tricks here: 1. Design libraries correctly - you should have polarity convention that matches your P&P and your AOI machi

We have already one desktop oven and a manual stencil printer. And we have a quite complete soldering bench with several JBC tools. We also have stock for all active elements we use. We normally relay on the PCB assembler to provide the passive comp
