circuit board

At the Royal Mint plant, piles of circuit boards are being fed into the new facility.

These objects are juxtaposed alongside digital detritus — circuit boards, resistors — that line the wooden boxes like wallpaper.

On some models, the battery is not so easy to remove because it’s soldered to the circuit board.

Damaged circuit boards, such those with cracks or warping, can in some cases be repaired.

They also created a low-cost, printed circuit board with built-in digital microfluidics, which the emitter is soldered to.
