D. Contact Holes
The holes in the pc board for compliant pin and through--hole contact tines must be drilled and plated
through to specific dimensions given in Figure 5.

3.4. Spacing
Plug and receptacle clearance zones and spacing must be considered regarding the backward compatibility
with CHAMP .050 Series I SCA--1 plugs when mated to CHAMP .050 Series I Blindmate SCA--2 receptacles
and SCA--1 receptacles when mated to SCA--2 plugs. See Figure 6.
3.5. Plug and Receptacle Placement
The plug and receptacle should be handled only by the housing to avoid deformation, contamination, or other damage
to the contact tines.
A. Manual
The plug or receptacle number one contact tine must align with the number one contact tine hole in the pc
board. All contact tines must start into the pc board; then, when the boardlocks start to engage the pc
board, the plug or receptacle can be pressed until it seats on the pc board.
B. Robotic
The robotic equipment must be adjusted to feed, pick up, and place the plugs and receptacles on the pc
board with an accuracy of 0.25.
C. Stability on PC Board
The plug and receptacle boardlocks have gripping shoulders that pass through the pc board at the same
time the contact tines are inserted through the pc board. They lock into position when the housing is
seated on the pc board. The initial forces are 62 N maximum for insertion and 13 N minimum for
extraction. See Figure 7.

3.6. Soldering
After the plug or receptacle is snapped into the pc board, the boardlocks must be soldered at the same time as the
contact tines during the soldering process.
It is recommended using SN60 or SN62 solder. Refer to Paragraph 2.4 for instructional material that is
available for establishing soldering guidelines. These plugs and receptacles can be soldered with wave process
provided the temperatures and exposure time meet the requirements given in Figure 8.

A. Flux Selection
Contact tines must be fluxed prior to soldering with a mildly active, rosin base flux. Selection of the flux will
depend on the type of pc board and other components mounted on the board. Additionally, the flux must
be compatible with the wave solder line, manufacturing, health, and safety requirements. Call PRODUCT
INFORMATION at the number at the bottom of page 1 for consideration of other types of flux. Flux that is
compatible with these plugs and receptacles are provided in Figure 9.

B. Cleaning
After soldering, removal of fluxes, residues, and activators is necessary. Cleaning methods depend on the
type of flux used. Consult the supplier of solder and flux for recommended cleaning solvents. Common
cleaning solvents and related temperatures that can be used without any adverse effects on contacts or
housing are listed in Figure 13. For any solvent not listed, contact PRODUCT INFORMATION at the
number at the bottom of page 1 for suitability.
