  • • SAS will not be responsible for any incompatibilities of the PCB finish with the assembly technology (example: HASL for fine pitch or BGA), impacting the quality of the assembly.
  • • Failure to comply with these constraints may require the production of tools, which will be billed to you directly and the cost of which will be specified to you upon receipt of your PCB.
