Printed circuit board header attachment station

摘要: The printed circuit board (PCB) header attachment station mounts a onto PCB having preexisting solder joints, such as underneath direct mount IC chip. apparatus applies soldering paste to lands configured receive the pins of header; nests component in stacked alignment with order bring into contact respective lands; heats temperature approaching reflow pre-existing joints; and actuates compliant heating block or bar heat an extent sufficient for conduct enough locally on corresponding without reflowing joints. local precludes surrounding joints which may coalesce under chip render defective.
