Description

• US Patent # 7,207,811 B2
  
  120-M-221-SMD header is a multi-pole 5 mm connector that performs total dynamic adaptability to planar variations of PCB. Contact pins of this product are capable to move in all X, Y, Z directions. The first result of this total co-planar adaptability, is the fact that even the slightest variation of the PCB planarity is compensated during the reflow soldering process. The second result is the elimination of the CTE (Coefficient of Thermal Expansion) mismatch. It is because of its particular design, that pins are capable to compensate the negative effect of the different expansion parameters of both thermo resistant material of the plastic housing and the Epoxy material of the PCB. It has been computed that for an extreme expansion case, the plastic housing could move on OX direction as much as 0.1 mm. In the majority of the cases the impact of such differential move would fracture or dislocate the solder contact area between the pin and the PCB. This phenomena is totally avoided through the special pin design. This connector type brings therefore a breakthrough solution into the SMT industry: total co-planarity dynamic adaptability and elimination of CTE mismatch.
  
  Type 120-M-221-SMD terminal block has been specially designed to allow effective potting of PC boards. The molding design prevents seepage of the potting material into the wire clamping area up to 7.5 mm (0.295 in.) from the board. Removable thermo resistant pick caps are supplied when packed in tape and reel. This allows automated pick & place applications.
