Termination method of soldering connector onto PCB. Through hole (TH), surface mount (SMT) or Hybrid.
The horizontal hybrid types allow better control over co-planarity of SMT contacts and alignment of thru hole pins. From an inspection point of view the hybrid allows customers to inspect the connectors post processing, as viewing the inner rows of contacts on pure SMT parts is difficult. The hybrid type may be processed using paste in hole, which allows a single process.
