Figure 3. HSDL-3000#007/#017 PCBA – Adjacent land keep-out and solder mask.

• Adjacent land keep-out is the

maximum space occupied by

the unit relative to the land

pattern. There should be no

other SMD components within

this area.

• “h” is the minimum solder

resist strip width required to

avoid solder bridging adjacent

pads.

• It is recommended that 2

fiducial cross be placed at mid-

length of the pads for unit

alignment.

Note: Wet/Liquid Photo-

Imageable solder resist/mask is

recommended.

2.0 Recommended Solder Paste/

Cream Volume for Castellation

Joints

The recommended printed solder

paste volume required per

castellation pad is 0.30 cubic mm

(based on either no-clean or

aqueous solder cream types with

typically 60 to 65% solid content

by volume).
