Overview
The datasheet provides detailed specifications for the TCQ Electronics Corporation Header Assembly, Mod II, a high-temperature, single-row, vertical plug connector with breakaway capabilities. The document includes dimensions, material composition, plating details, and recommended mounting instructions for use with a 0.063-inch thick printed circuit board (PCB) and a 0.012-inch stencil.
Detailed Specifications
The header assembly is designed with multiple dimensions specified in inches with corresponding millimeter conversions provided in brackets. The dimensions cover various attributes of the assembly, including post lengths and the spacing between the posts, which are consistent at 2.54mm (0.100 inches). The datasheet specifies the dimensions of the post tips and advises on the true position tolerance when the headers are mounted onto a PCB.
The document further defines the plating specifications noting that the contact area is plated with 0.00038 inches of gold, and the solder tail is coated with a matte tin-lead or tin finish over a nickel underplating. Housing is constructed from LCP (Liquid Crystal Polymer) in black, while the posts themselves are made of brass.
Material and Plating Information
Material for the housing is identified as LCP with a color specification of black. For the plating, the document specifies a gold plating of 0.00038 inches in the contact area, matte tin-lead or matte tin on the solder tail with a minimum and maximum thickness given, and an all-over nickel plating of 0.00127 inches. The part numbers are provided alongside the information on plating for each available number of positions.
Mounting and Breakway Feature
Recommended PC board mounting dimensions are provided for those using a 0.063 inch (1.60mm) thick PCB with a stencil thickness of 0.012 inches (0.305mm). Assembly can be broken into the desired number of positions as needed to fit a specific requirement, ensuring flexibility in its use.
Additional Details
The datasheet lists reference numbers for part numbers related to the number of positions available. The sheet also notes the document status as a controlled document and references for application and configuration specs. Additional details such as the release and approval dates, the name of the person who approved the specifications, and the document number are included for traceability.
