INTRODUCTION:

      Parlex, a Methuen, Massachusetts based corporation is a world leader 
in the flexible interconnect industry.  Founded in 1970, the Company has 
maintained a focus on flexible and rigid flex circuits and has been a prime 
influence in the development of this technology.

      Parlex has a large engineering staff and is active in the development 
of new interconnect technologies.  The Company is highly capitalized and has 
the proper organization to support a technology sharing venture.  CSIST can 
expect the highest level of support from every level of this organization.

         Qualification Program for Rigid-Flex Printed Wiring Boards


Parlex will assist CSIST in the fabrication of Qualification Rigid-Flex 
printed wiring boards.  This program is designed around the ten layer Rigid-
Flex board used to qualify manufacturers to fabricate boards which will be 
in compliance with MIL-P-50884C, the Specification for Flexible and Rigid-
Flex Printed Wiring and MIL-STD-2118, the Design Requirements for Flexible 
and Rigid-Flex Printed Wiring for Electronic Equipment. 

The board to be fabricated during this program will be manufactured using 
the artwork for the IPC-A-100043.  This has the advantage of incorporating 
several degrees of difficulty which allow for the evaluation of your process 
technology as well as demonstrating the ability to fabricate complex Rigid-
Flex boards. 

Parlex has designed this program so that upon successful completion, you 
should be able to fabricate Zone B level boards and pass the qualification 
of Zone B level by the Defense Electronics Supply Center (DESC).
