The biggest costs in hardware development aren't in the PCBA, but in the time between iterations.

A creative trick: use an extra PCB as an alignment and pressing tool for press-fit prototypes.

How a mold mark almost caused a wrongly placed IC, and why ProtoPhotos are essential.

Test structures, mask outlines and local fiducials for reliable fine-pitch BGA assembly.

When components are designed for conductive adhesive instead of standard soldering.

If sample 1 or 2 already tells you enough, it's a waste to assemble the rest.

For components, a second source is obvious. For PCBs, almost nobody arranges it.

Reliable and vibration-resistant, but often impractical in the prototype phase. Practical tips.

When 1 oz copper is not enough: benefits, lead time and a smart prototyping strategy.

How DeltaProto's iteration approach combines speed and cost savings, and why green PCBs are better for AOI.

Looking back on a year full of lessons, iterations and improvements.

Microscopically small metal hairs that grow spontaneously and can cause short circuits.

Sometimes the best choice is not either buying or making it yourself, but a combination of both.

One mistake in the measurement system and your component doesn't fit the footprint. A very common pitfall.

With BGA's or fine-pitch components, vias in a pad are unavoidable. How we shorten lead time by filling vias ourselves.

How we build our own TestJigs to program and test PCBA's, and what we learned through iteration.

80% of all ProtoPCBA's need at least one extra iteration. This one required a creative soldering solution.
