Would distilled water be considered deionized? I know that is not the typical process to produce deionized water but it is widely available in grocery stores if you need small amounts.

Distilled water is a perfectly adeqaute alternative to DI water. As you say, they just are produced using different processes and technically could have slightly different properties, but for every day requirements can be used interchangeably.

Distilled water normally removes ions as well as dissolved solids (non-volatiles). Deionized water has been stipped of ionic species, but non-ionic organics are left behind.

Remember, deionized water is very corosive. If the water is too deionized, 10 mega ohm, it will leach the ions from exposed metals. I had a stencil cleaner where the welds completely dissolved. The stainless steel tank was fine but the welds were

Yes, many ICT can test your RS485 board. You need: * Test program * Test fixture OR you could buy a RS485 tester.

On going from 24v to 18v, try: * Voltage regulator * Resistor divider * Transformer On not generating heat or loosing energy, the laws of physics already are pretty well fixed.

A switching regulator should give you upwards of 85% efficiency. National Semiconductors 'Simple Switchers' are pretty good, and they have some good design tools on their site.

What are ghost feeders? I've been creating a feeder for each slot and teaching each one individually before running a job. eg. Using an 8mm tape in slot 20 = "8mm Tapeslot20" or 12mm tape in slot 56 = "12mm Tapeslot56"

You may be creating more problems by teaching feeders. We use one type of 8mm for whatever amount of feeders we have loaded. You shouldn't have to teach 10-8mm feeders with 10 different feeder names. Use only one.

I think it might be the feeder banks, that is causing the problem. I've tried picking a SOT-23 component using head 2 spindles 1-4 from a rear feeder bank and it is picking off centre. Doing exactly the same, but putting the feeder in a front bank it
