0.4 mm Pitch, 0.6 and 0.8 mm Height, Board-to-Board and Board-to-FPC Connectors BM20 Series Receptacle Existing products BM20 10.4mm 10.48mm A 22.3% reduction in size Existing products BM20 2.3 10.48 2.98 10.4 2 2 =About 31.0mm = About 24.1mm Header BM20 Existing products Features 1. High density mounting capability 9.32mm A space saving design that keeps the connector 9.4mm compact, but still maintains an adequate vacuum area (no less than 0.7mm wide). Board occupied area A 27.1% Depth DS: 2.3 mm DP: 1.78 mm reduction in size Existing products BM20 2. Reliable contact performance 2.46 9.32 1.78 9.4 2 2 Even though the mated height is low, the BM20 still = About 16.7mm = About 22.9mm leads it class in maximum effective mating lengths for each mating height. <Effective Mating Length> Height 0.8 mm: 0.2 mm Vaccum pick-up Height 0.6 mm: 0.15 mm % , The addition of the two point contact system adds % , more reliability to the contacts. 3. No restrictions to PCB pattern design *1 for the 0.8 mm height connector This series utilizes a thin wall to insulate the bottom surface of the connector and maintains an effective mating length of 0.2 mm. This removes any restriction for PCB pattern layout design under the connector. Note *1: There are some restrictions for the 0.6 Mating diagram (cross section) mm height style. H=0.8 4. Enhanced mating operations The structure uses guide ribs to ease the mating Molded Bottom process and offers a self alignment range of up to surface structure 0.3 mm. A clear tactile click is used as an indicator to the user that the mating process was completed. 5. Drop and shock resistant structure Dimples were designed into the contacts to increase their retention force and to absorb the shock delivered from a drop or other impact. Molded Bottom 6. Debris resisting design H=0.6 surface structure When mated, the connectors design covers the contacts which help to keep dust and other debris away from the contacts. The SMT leads are kept very close to the connector housing which also helps to prevent shorts caused by debris on the exposed contacts 1 2013.11 1.78 mm 2.3mm 2.46mm 2.98mmBM20 Series0.4 mm Pitch, 0.6 and 0.8 mm Height, Board-to-Board and Board-to-FPC Connectors Product Speci cations Operating - 35 85C Storage Temperature - 10 60C Rated Current 0.3A Temperature Range (Note 1) Range (Note 2) Ratings Operating Humidity Storage Humidity 40 70% Rated Voltage AC, DC 30V 20 80 Range Range (Note 2) Items Speci cations Conditions 1.
