“How much does it cost to build one of these?” It depends… When an aerospace customer needs a new printed circuit assembly built for a legacy system, invariably their first question is “how much will it cost?” Building a new assembly can be relatively straightforward—or impossible—to accomplish. It depends. Is it build-to-print? Assuming the engineering dataset is complete, and you can wrestle it to the ground, build-to-print can be cost-effective. Reverse engineering, or reproducing the engineering data set and getting regulatory acceptance, is by far the costlier path. Here I’ll address some of the challenges of build-to-print for legacy circuits.     New Old Stock. The first consideration is whether the components called out in the drawing package are still available. And make sure the available stock is actually new, … Read More +
