Build-up preparation and pressing

Pre-preg is one of the most important materials to produce printed circuit boards, together with inner layers and copper foils.

Inners preparation before Multilayer lamination

Here we are again to continue our virtual factory tour to better understand all process steps necessary to produce PCBs.

Inner Layer’s Automatic Optical Inspection (AOI)

What could help to start in the very best way the process to manufacture a PCB is to combine SPC together with Automatic Optical Inspection

Inner Layers Etching Process: "Acid" Etching

The portion of the process following the lamination and photoprinting phases corresponds to the dry film development phase - copper etching – dry-film stripping.

Statistical process control in pcb production

Quality was born as metrological control of the product and this concept developed in the 90s as basis of the first versions of the certifiable ISO 9001 standard.

From activation to photoprinting of the innerlayers

As reported in our first article, examining a basic cycle of a Multilayer product, the processes of
