GORE SMT EMI Gaskets and Ordering Information Grounding Pads Ordering Information Figure 2: Configuration of Carrier Tape, 8-mm Pitch All components of GORE SMT EMI Gaskets and Grounding Pads, including carrier tape, cover tape, and reels are 8.00 0.10 packaged according to EIA 481. The carrier tape is conductive 2.00 0.05 carbon-filled polycarbonate or polystyrene. Most of the parts 4.00 0.10 1.50 +0.10 are packaged in a 4-mm pitch carrier tape, with larger parts 1.75 0.10 packaged in 8-mm pitch (Figures 1 and 2). Tape is available in widths of 12 mm, 16 mm, and 24 mm, depending on the part geometry (Table 1). The A , B , and K pocket dimensions 0 0 0 5.50 0.05 12.00 +0.30 (Figure 3) vary based on the part dimensions as shown in 0.10 Tables 3 and 4. The peeling force of the cover tapes is between 10 and 100 grams. All cover tape is static dissipative and is sealed using 1.50 +0.25 a pressure-sensitive adhesive.

The inside diameter has three sprocket Thickness dimensions for the SMT GS5200 Series include the notches with a minimum diameter of 20.2 mm. The reels are shim (Figure 5), and all of the dimensions of the SMT Supersoft labeled on one side with the part number, the lot number, the Series include both the shim and the mechanical crimp date, and the number of parts on the reel. Reels are packaged (Figure 6). See Tables 3 and 4 for dimensions of each part, into cartons the number of reels per carton varies depending including corresponding specifications for carrier tape, reel, on tape width (Table 2). pocket, solder mask opening, and solder paste pads.

As other raw materials are introduced in production, e.g., metal shims, new lot numbers are assigned for the work-in-process items, but all raw material lots can be traced. Our supplier provides lot numbers for the carrier tape and cover tape. Gore records the operating conditions and all processes performed on each lot and stores this data in our System 9000 Quality Control Database. Page 2
