mSAP vs. Conventional PCB Fabrication

What Is mSAP?

Modified Semi-Additive Processing (mSAP) is a fabrication approach designed to overcome the limitations of traditional etching in Printed Circuit Board (PCB) industry.

Rather than beginning with a thick copper layer and removing most of it, mSAP starts with a thin copper seed layer. Copper is then selectively plated only where circuitry is required. The result is dramatically improved line definition, finer trace geometries, and higher routing density compared with conventional subtractive methods.

Crossing the Valley of Death in Semiconductor Packaging

AmTECH bridges R&D innovation with scalable, sub-micron packaging for photonics, medical, neuromorphic, quantum and DoD applications.

In today’s Industry 4.0 landscape, innovation is advancing at unprecedented speed, but many promising ideas still fail to scale beyond early prototypes. This critical gap, known as the “valley of death,” occurs when startups face the dual challenge of securing funding while needing access to advanced manufacturing capabilities.
