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 CAUTION ! 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.

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. NOTE i 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. SOLDERING PROCESS WAVE TEMPERATURE TIME (At Max Temp) Wave Soldering 260_C [500_F] 5 Seconds 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. FLUX TYPE ACTIVITY RESIDUE RMA Mild Noncorrosive COMMERCIAL DESIGNATION KESTER ALPHA 186 611 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.

Drying When drying cleaned assemblies and pc boards, make certain that temperature limitations of --48.4 to 40.5_C [--55 to 105_F] are not exceeded. CAUTION Excessive temperatures may cause housing degradation. ! 3.7. Checking Installed Plug and Receptacle All solder joints should conform to those specified in Workmanship Specification 101--21. The housing must seat on the pc board not exceeding the dimension given in Figure 14. Housing (Typ) 0.13 (Max) Plug or Receptacle Seated on PC Board Solder Boardlock Contact PC Board Figure 11 3.8.

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 apply only 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. .

Polarization The plug and receptacle are inherently polarized for mating. The keystone configuration of each plug or receptacle mating face prohibits the accidental inversion of mating plugs and receptacles. See Figure 14. Polarizing Keystone Configuration Figure 14 3.9. Unmating Plugs and Receptacles The plug and receptacle must be unmated by rocking them apart. One end should be free, but should not be pulled more than 5_ before rocking the same end back. This will release the opposite end, and the two will be freed or separated. See Figure 15. Plug and Receptacle Separated 5_ Max Before Rocking Them Apart Figure 15 3.10. Repair Damaged plugs and receptacles must be removed, discarded, and replaced with new ones. Plugs and receptacles with soldered contacts may be removed from the pc board by standard desoldering methods. For plugs and receptacles with compliant pin contacts, if pins are protruding from the pc board, pins must be pushed from the back with a flat rock, and if pins are buried, the housing must be pulled off of the top, then the contacts can be pulled from the pc board. 4. QUALIFICATION CHAMP .050 Series I Blindmate SCA--2 are Component Recognized by Underwriters Laboratories Inc. (UL) under File E81956, and Certified by the Canadian Standards Association (CSA) under File LR 7189. 12 of 14 Rev D 114- 6061 5. 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.
