On a pick-and-place line, those guides also prevent tombstoning by centering the part on the pads before the paste reflows. ## Surface Mount Termination — Reflow Profile Matters The Tape & Reel packaging feeds directly into a standard 8 mm carrier for automated placement.","metaTitle":"Hirose DF12D(3.0)-20DP-0.5V(81) Header, 0.50mm Pitch, 20 Pos","metaDescription":"Hirose DF12D(3.0)-20DP-0.5V(81) 0.50mm pitch header, 20 positions, 2 rows, 3mm stacking height, gold contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Board-to-Board Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.020\\\" (0.50mm)","Series":"DF12","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Board Guide","Mounting Type":"Surface Mount","Connector Type":"Header, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Obsolete","lifecycle_stage":"unknown","Height Above Board":"0.091\\\" (2.30mm)","Number of Positions":"20","Mated Stacking Heights":"3mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/801352e576480b4c19254a5dc0f8f8a7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF12D(3.0)-20DP-0.5V(81)/alternatives.json"},"ai":{"faq":[{"question":"Is DF12D(3.0)-20DP-0.5V(81) obsolete?
