Case Studies of Our Medical PCBA

Project Requirements:

The medical PCBA is a 12-layer rigid-flex board with a size of 35mm×30mm×6mm, requiring 99.8% first pass yield (FPY), 15-20 years of maintenance-free service life, and compliance with ISO 10993 biocompatibility standards.

Challenges:

challenges included ±75μm interlayer alignment accuracy for rigid-flex transition zones, controlling soldering void rate for 0.4mm pitch BGA, and ensuring no flux residue in a Class 10000 cleanroom environment.

Solutions:

We implemented stepped lamination for rigid-flex zones, used laser-mechanical hybrid drilling for precision control, and adopted nitrogen-protected vacuum reflow soldering to reduce void rate below 5%. Free DFM analysis optimized wiring to avoid signal crosstalk, and MES system enabled full-process traceability.

Results:

The project achieved 99.8% FPY, passed 1000 cycles of temperature cycling (-40℃~125℃) testing, and met NMPA and CE MDR requirements. The medical PCBA successfully entered clinical trials, with stable performance in accelerated aging tests simulating 15 years of use.
