Important Criteria for Selecting a Socket Source
When selecting an image sensor socket source, consider the following:
• How many years of experience does the source have in designing and producing
image sensor sockets, in particular with pitches as tight as 0.032 in. (0.8 mm) for land grid array (LGA) and leadless chip
carrier (LCC) sockets, and 0.039 in. (1 mm) for pin grid array (PGA) sockets?
• Does the source have socket cross-
references to all the major image sensor
brands used in industrial, aerospace, defense, scientific, and medical/life science applications — for example, Gpixel, Sony, ams (formerly CMOSIS), ON Semiconductor, Teledyne e2v, Canon, BAE Systems
(formerly Fairchild Imaging), and Luxima Technology?
• Does the source have the endorsement of, and a close working relationship with, the leading image sensor makers?
• Does the source have sockets available for PGA, µPGA, LGA/BGA (ball grid array), LCC, and dual in-line packages?
• Does the source offer both thru-hole and surface-mount terminal options?
• Does the source offer a terminal option that is specially designed for high-shock and high-vibration applications?
• Does the source offer a solution that delivers individual socket pins, or separate sockets, on a firm carrier — for fast, accurate loading in low-profile environments, or environments in which a socket insulator would interfere with a heat sink or other devices already on the printed circuit board?
• Does the source offer sockets that provide heat and noise dissipation, without the
power or space required by thermoelectric coolers?
• Does the source offer a low insertion force socket for high-pin-count µPGA packages with 0.050-in. (1.27-mm) pitch?
• Does the source use high-speed methods, tools, and machines for loading plated contacts into plated terminals?
• Does the source use high-speed methods, tools, and machines for loading plated
terminal assemblies into socket insulators?
• Does the source have long-established relationships with image sensor socket raw material suppliers?
• Is the manufacturing facility ISO9001:2015 certified?
