Discussion Details:

  • Lars had prepared a set of slides for our review.
  • Lars has all hole patterns needed
  • Lars asked if anyone knew of a standard for measuring single pin retention force?
  • Lars discussed final hole diameter, should the variation in hole diameters be achieved only by varying the plating thickness or should the plating thickness be constant and the final hole diameter be varied by using different drill diameters. After a discussion it was decided to go with a constant plating thickness process.
  • We discussed material fracture toughness and its impact on measurements. After a discussion it was decided to go with a single material. Tentatively Isola 370 HR.
  • We discussed layer count in the TV. A 2 layer design vs a 4 layer design. We concluded a 4 layer design with the middle two layers close to the top layer. Suggest layer 2 and 3 to be 5 – 6 mils from the outside layers.
  • We discussed Gas Tight testing. A third party test house was identified as a resource for gas tight testing. No decision was made on gas tight testing.

Actions Items:

  • Anyone knowing of a retention force measurement standard please let us know
  • Jack to contact Contact Research Corp. in Attleboro, Mass.

Next Meeting:
