FCI Basics D-Sub Pin-in-Paste Connectors are now available in Pin-in-Paste (Through Hole Reflow) versions in standard and compact form factors. Pin-in-Paste technology (PiP) allows the use of Through Hole products in SMT manufacturing processes. The connectors use high-temperature thermoplastic that can withstand reflow soldering temperatures up to 260??C to facilitate PiP soldering.
