Construction
The information below is only a guide for quoting; we can provide more details on request.
PCB Specifics
a)
Core material shall be fiberglass-reinforced polyimide composite. Corresponding metal clad
laminates and pre impregnated bonding material (Prepreg) PWB suppliers are allowed to
modify prepreg construction if changes met IPC-4101 equivalence requirements.
b)
High Tensile Elongation copper foil shall be used on Internal and external copper layers (
HTE copper) as per IPC-4562.
c)
The surface plating shall be Electroless Nickel Immersion Gold (ENIG). ENIG plating shall be a
No-Selective process which means that ENIG plating is applied on every part of exposed
conductors and before solder mask application.
PCB construction procedures
There will be a couple of PCB construction procedures that will need to be followed. These are not
too difficult but the techs will need to know in advance.
a)
The PCBs need to be baked to remove all the moisture before assembly and the work must
be done within a few hours of the baking. They can be baked and stored in sealed bags that
can be remain sealed until assembly is complete.
b)
The construction will be done using Schlumberger PWA Acceptability Rules for Electronics
Assemblies Specification (100066225).
