Rule 1: Clean it as soon as you see it! Don't let it dry. It's harder to clean up and can be easily injested when in a dry powder form. Rule 2: See rule 1

Let me make it simple than! one controller should be enough for a 400 sq ft room as a good rule of thumb. Although there are many factors that can affect this rule of thumb so read your graphs and take the approciate action. Dave

Let's examine some scenarios: What if... ...No solder sample available and you must profile a "live" board (rules out epoxy). ...Lead free build (rules out lead bearing alloys)

Hi, Just wondering what, if any, design rule checks each of you do prior to running new products. Comments from contract manufacturers particularly welcome. regards Dougs

How many times can you safely run a board across the wave solder? We have an unwritten rule here saying that twice is all that we can do. But it has been an unwritten rule for so long that no one knows where it orginated. Thanks for your imput.

Does anyone know af a software package that can run a design rule check on gerber files. It would be great if it were a free package.

Yes, it OK to mount axial PTH component as radial PTH, if that's what you're asking. * There are no rules for orientation. Pick something and stick to it. We like to be able to read the component value / orientation from the top towards the board.

Never automatically rule out that the parts were received defective. Although at 1 in a thousand it would be difficult to rule out.

There are some "rule of thumb" design approaches for circle apertures for BGA's. Does anyone use rule of thumb formulas for square/squircle apertures for BGA? If so, what are they?

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow
