What is the recommended PCB hole size for the PH through-hole headers for harder resin boards?

The following are the recommended drill hole sizes for the most common PCB materials:

JST Part Numbers

B*B-PH-K-S  (LF)(SN)
S*B-PH-K-S  (LF)(SN)

Replace "*" with the applicable number of circuits (2 ~ 16).

Recommend PCB hole size (all dimensions are in mm):

Paper-based epoxy resin

Ø0.70 ~ 0.75 for 2 circuits
Ø0.75 ~ 0.80 for 3 ~ 16 circuits

Glass-based epoxy resin (without through-hole)

Ø0.70 ~ 0.75 for 2 circuits
Ø0.75 ~ 0.80 for 3 ~ 16 circuits

Note: Hole size of the paper-based epoxy PC board and glass-based epoxy resin PC board
(without through hole) is the value set for the drill hole (NC processing).

Glass-based epoxy resin (with through-hole)

Ø0.80 ~ 0.85 for 2 circuits
Ø0.85 ~ 0.90 for 3 ~ 16 circuits

Note: Hole size of glass-based epoxy PC board (with through-hole) is the finished dimension
after plating through-hole.
