WEB EXCLUSIVE: Samtec Inc., New Albany, Ind., a global producer of a broad line of electronic connectors, eliminated production defects in its largest-volume connector series by switching to Vectra E488i, a low-warpage liquid-crystal polymer (LCP) grade from Ticona Engineering Polymers, Florence, Ky. This halogen-free, UL 94V-0 grade is designed specifically to give flatter thin-wall electronic parts such as Samtec’s low-profile socket strip CLP series connectors, which are used in board-to-board interconnect systems. These connectors have up to 50 contacts per row and a 0.005-in. wall thickness. They must maintain extremely tight dimensional tolerances after lead-free reflow soldering at 260 C. This high-flow, fast-cyling LCP grade contains glass and mineral fillers. Samtec’s custom molder had been experiencing intermittent filling problems and bowing of parts with other commercial LCP grades. “Now, with the switch to Vectra E488i, our molder increased its molding run and eliminated its sorting and scrapping headache, and Samtec is receiving CLP connectors that are filled an in spec,” says Jim Hahn, Samtec product engineer. “Not only that, but we’ve been able to improve the critical pin retention by about 10% during the lead-free soldering process.”
