Estimating the term…
A lower needle adapter has lower, resilient contact needles and an upper needle adapter has upper, resilient contact needles which are provided for contacting of both sides of component equipped printed circuit boards. Defined contacting conditions having correspondingly high contact reliabilities are achieved in that the printed circuit boards are pressed against opposite pressure rams arranged in non-yielding fashion, being pressed thereagainst by resiliently fashioned pressure rams. When resilient, upper pressure rams are used to press the printed circuit boards against lower pressure rams which are adjustable in height in two stages, then a both-sided, two-stage contacting can be realized in a simple way with corresponding, additional, shorter lower and upper contact needles.
A testing device for equipped printed circuit boards having a lower needle adapter which carries resilient, lower contact needles arranged test-specimen-associated for contacting an underside of the printed circuit board, and having a plurality of upper pressure rams arranged test-specimen-associated, for contacting an upper side of the printed circuit board comprising an additional upper needle adapter carrying resilient upper contact needles arranged test-specimen-associated;
A testing device for component equipped printed circuit boards having an underside and an upperside, said testing device having a lower needle adapter carrying resilient lower contact needles arranged test-specimen-associated for contacting the underside of the printed circuit baord and also having a plurality of upper pressure rams arranged test-specimen-associated for engaging the upperside of the printed circuit board, comprising;
A testing device for component equipped printed circuit boards having an underside and an upperside, comprising:
