I have received a couple of comments and questions relating to the language of specifying printed circuit boards.  As it turns out, a lot of users, and specifiers are confused by terms in common use….only because different fabricators use different language.

One that trips everybody is the word “array”.  Let us try to help.

All board fabricators construct  boards in a multi-up patttern within the dimensions of a standard “master” panel in their factory.   For example, we use one of three standard sizes - 12″ x 18″, 16″ x 18″, or 18″ x 24″ .  Our internal tooling is set for these “master” panel dimensions.  Doing this  speeds production, reduces scrap, and keeps your cost low.  Your individual boards are then stepped ( stepped means repeated many times ) onto this panel size.

From this master panel, we rout out (  separate ) the parts you want either to their final shape…or into a smaller panel with multiple parts ( the array ).  The dimension of this array of parts is defined normally by the custmer and is driven by tooling requirements for assembly.

So…we use the term “array” to refer to a panel of  ”x”  number of finished boards, either scored or routed for quick snap out by the customer.

Most important…when you are placing orders please be certain to specify what your “quantity” refers to…individual boards or your array of boards ready for snap out.  Confusion here is common.

Have any other industry terms you need help with?  Send your questions or comments and we will try to help.

After the 4th of July break the electronics industry usually goes into a shallow hibernation…but often, when we are coming out of a recession,  summer is strong….what do you think?  Are things about to break loose in your business?

I am getting mixed messages out there concerning the health of the economy. Most customers tell us things are better…more tail wind than head wind is one quote.

One thing we all have been waiting to feel the benefit of is government stimulus money.   One source tells me that China was able to get their stimulus package on the street in a couple of weeks.  It is not clear to most I speak with that any government stimulus money has left Washington as yet.  Has your company benefited from any Washington money?

I would be intetrested to hear from you.
