INTRODUCTION This specification covers the requirements for application of CHAMP .050 Series I Blindmate plug and receptacle SCA- -2 for printed circuit (pc) board application. These plug and receptacles are available in 20, 40, and 80 positions and contain through- -hole contacts or compliant pin contacts on 1.27 centerline spacing. The plugs are available in vertical and straddle mount; and the receptacles are available in right- -angle, vertical, press- -fit vertical, extended height press- -fit vertical, and extended height vertical. These connectors are fully compatible with CHAMP .050 Series I SCA- -1 board- -to- -board connectors. The plugs and receptacles contain boardlocks to provide additional stability when placed on the pc board. End cavities are marked with a number to provide circuit identification. The plug and receptacles may be placed on the pc board by hand or automatic application tooling. When corresponding with personnel, use the terminology provided in this specification to facilitate your inquiries for information. Basic terms and features of this product are provided in Figure 1.

REQUIREMENTS 3.1. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the housings. B. Shelf Life The plugs and receptacles should remain in the shipping containers until ready for use to prevent deformation to the plugs and receptacles. The plugs and receptacles should be used on a first in, first out basis to avoid storage contamination that could adversely affect signal transmissions. C. Chemical Exposure Do not store the plugs and receptacles near any chemicals listed below as they may cause stress corrosion cracking in the contacts. Alkalies Ammonia Citrates Phosphates Citrates Sulfur Compounds Amines Carbonates Nitrites Sulfur Nitrites Tartrates Greenerd is a trademark.
20-Position Straddle Mount Plug 40- and 80-Position Vertical Plug 114- 6061 Rev D4 of 14 C. Recommended Layout The boardlock holes and contact holes in the pc board must be precisely located to ensure proper placement and optimum performance of the plug or receptacle. The pc board must be designed using the dimensions provided in Figure 4. The “X” and “Y” symbols on the pc board layout represent customer established datums. They are the origin for the basic dimension (XXX and YYY datum), the point from which ALL hole positions must be located. The layout dimensions apply to either side of the pc board.

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. Figure 5 1.27 (Min) Pad Diameter 0.025- -0.050 Copper Plating (Max Hardness of Copper to be 150 Knoop) 0.008- -0.015 Tin Lead Plating 0.87- -0.93 Drilled Hole Diameter 0.72- -0.88 Finished Hole Diameter (After Plating) 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. CAUTION

B. Dimension Mating dimensions are required to ensure full mating of plugs and receptacles with a minimum contact wipe of 1.48. The mating dimensions must be considered when determining the method of mounting the plug or receptacle and the thickness of the pc board. These dimensions applyonly when using TE Connectivity plugs and receptacles. If other plugs or receptacles are used, refer to industry specifications for SCA- -2 from the Small Form Factor Committee and Electronic Industries Alliance (EIA). See Figure 13.

- TOOLING For pc board applications where solder is used, no special tooling is required for hand placement of these plugs and receptacles on the pc board, however the following information should be considered. Tooling part numbers and instructional material packaged with the tooling are shown in Figure 16. 5.1. Application Tooling Application tooling provides the force required to insert the plug or receptacle contacts into pc board holes. For low- -volume production, commercial hand- -operated arbor presses, such as Greenerd 3A or 3B manual frame assembly are available. The arbor presses must be fitted with an adapter kit as described in 408- -9027. Power units are designed for high- -volume production. SM- -3 machine is a pneumatic bench- -mounted power unit controlled manually with pc board sensing or pressure sensing operation. 5.2. Seating Tool The seating tool must be used with application tooling for seating vertical receptacles with compliant pin contacts. During seating, the tool aligns the plug or receptacle to ensure proper insertion into the pc board and prevents damage to the contacts. Each tool is specifically designed for the number of rows in a plug or receptacle. 5.3. PC Board Support A pc board support should be used to prevent bowing of the pc board during the placement of a plug or receptacle on the board. It should have flat surfaces with holes or a channel wide enough and deep enough to receive the contact tines and boardlocks during installation of the plug or receptacle onto the board. 5.4. Robotic Equipment The robotic equipment must have a true position accuracy tolerance of 0.25 to properly locate the plug or receptacle for insertion. This includes gripper and fixture tolerances as well as equipment repeatability.
