2. Mezzanine manufacture Progress
PCB manufacturer delayed through the processing due to technically challenging design.
Shipped 20 to assembler ( Patronics Ltd ).
15 assembled boards delivered to DL 2/12/09.
5 assembled boards failed final quality control at Patronics. Pads had lifted after re-work.
After visual inspection at DL.
10 OK for use.
1 broken track and lifted resistor
1 solder whisker between resistors ( can repair )
3 solder on ASIC pads
Assembled to copper block and found a component fouled. Mechanical workshops removing 0.2mm copper to solve the problem.
Creating 5 kits with mezzanine card, mounting pins and copper block with heat conducting foam pad in place for despatch to RAL.
