3.5. PC Board
Rev B
A. Material and Thickness
The pc board material shall be glass epoxy (FR- -4 or G- - 10). For single plane application, the pc board
thickness shall be a minimum of 1.40. For mid plane application, the backplane thickness shall be a
minimum of 3.8.
B. Tolerance
Maximum allowable bow of the pc board shall be 0.03 over the length of the connector.
C. Holes
The contact holes must be drilled and plated through to specific dimensions. The plating type and
thickness and finished hole size must be as stated to provide unrestricted insertion of the contacts.
See Figure 6.
Pc boards can be back- - drilled (counterbored) for signal integrity performance using no more than the
overall plating thickness dimension provided in Figure 6.
D. Layout
The holes in the pc board must be precisely located to ensure proper placement and optimum
performance of the module. The pc board layout must be designed using the dimensions provided on the
customer drawing for the specific module. Reference sample of the recommended pc board layouts are
shown in Figure 7.
