Product Data Sheet Amphenol(R) Universal "Header Assembly" for Flex Print/PC Board Mounting No. 169-3 Mounts to all MIL-DTL-38999 and MIL-C-26482 Connectors The use of connectors with printed circuit termination is rapidly gaining popularity due to the rise of high volume, vapor phase or wave solder manufacturing processes. Termination of this style of connector to flex print or a printed circuit board represents a major cost in the manufacturing process for users. When adding flex or printed circuit board assemblies to an expensive filter or filter/transient protection connector, the total cost of a failed solder joint, a bent pin, or an unanticipated electrical failure becomes prohibitive. The universal header assembly from Amphenol will provide for easy separation of the connector from the board on these occasions. Header Assemblies Provide Cost Savings Incorporation of the header assembly provides the user with time and cost saving potentials. These header assemblies can be vapor phase or wave soldered to flex or printed circuit boards prior to the receipt of the EMI/EMP connector. Headers can be installed to standard connectors, allowing for electrical testing that would adversely affect the sensitive diodes, MOV's or capacitors in the EMI/EMP connectors. Expensive connector assemblies can be easily removed from and reattached to the header assembly as the manufacturing process dictates. Mounting Applications Shell modifications are recommended, but are not necessary. The header assembly can be attached to connectors with standard flange placement or directly to the circuit board. The ideal application would involve either a single flange moved all the way to the rear of the connector or a double flange. Cinch nuts can be installed in either flange to allow easier mounting to the panel or the header assembly. The forward flange would mount the connector to the panel; the rear flange would be used to mount the header assembly. Various types of captivated or loose attaching screws can be utilized for unique applications. Amphenol universal headers are slotted to allow mounting to all series of MIL-DTL-38999 or MIL-C-26482 connectors without special alterations. They are of similar dimension as the flange of the mounting connector and would be approximately .185 inches (4.70 mm) thick. Incorporates a Shorter Pin/Socket Contact The heart of the header assembly is a short pin/socket contact. The tail of the contact would accommodate standard through-hole diameters and thickness of the flex or printed circuit board materials. The socket is imbedded in the molded material, making electrical engagement with the printed circuit tail of the connector. Headers provide easy separation of the connector from the PC board. Cylindrical Configuration * 3 PCB stickout dimensions are available. * Size 22D contacts use .175 thick headers * Size 16 to 20 contacts use .195 thick headers * Consult Amphenol, Sidney NY for additional configurations. * Headers for cylindrical connectors accommodate up to 128 pins. Consult Amphenol catalogs for mating connector contact layouts (12-092 and 12-090 for MIL-DTL38999 and 12-070 for MIL-C-26482) Mounting to Rectangular ARINC Connectors * Headers for ARINC connector arrangements accommodate up to 150 pins * Consult Amphenol, Sidney, NY for ARINC configurations and detailed dimensions. Materials * Body is molded from Torlon or PPS (Polyphenylene Sulfide) * Electrical engagement areas of the header contact are plated with .00003 inches minimum of gold over .00005 inches minimum of nickel.
