Title (EN) AUTOMATIC TESTING SYSTEM FOR PRINTED CIRCUIT BOARDS
(FR) SYSTEME AUTOMATIQUE D"ESSAI POUR DES PANNEAUX DE CIRCUITS IMPRIMES
Abstract: front page image
(EN)Electronic circuits mounted on printed circuit boards, particularly circuits used for television receivers, are placed on a palette which is transferred by a conveyer. During transfer, test probes check whether or not the necessary parts are on the board as well as the suitability of their values to discriminate between defective circuit boards and those that pass. Then test probes monitor the characteristics of the parts and, if any require adjustment, this is automatically performed by a control circuit which controls a driver circuit. When the operational characteristics cannot be brought into predetermined limits by such adjustment, the circuit board is rejected as being defective. Thus, only circuit boards which have been properly adjusted are selected. In this manner, the selection and necessary adjustments may be made rapidly on a single conveyer line.
(FR)Les circuits electroniques, montes sur des panneaux de circuits imprimes, en particulier les circuits utilises dans les recepteurs de television, sont places sur une palette qui est transferee par un transporteur. Pendant le transfert des sondes d"essai verifient si toutes les pieces necessaires sont sur le panneau ainsi que leurs valeurs afin de distinguer les circuits defectueux. Puis les sondes d"essais controlent les caracteristiques des pieces et, si l"une d"elles necessite un ajustement, celui-ci est automatiquement effectue par un circuit de commande qui commande un circuit d"operation. Lorsque les caracteristiques operationnelles ne peuvent pas etre ramenees dans des limites predeterminees par un tel ajustement, le panneau de circuits est rejete comme etant defectueux. Ainsi, seuls les panneaux de circuits qui on ete parfaitement montes sont selectionnes. De cette maniere, la selection et les ajustements necessaires peuvent etre rapidement effectues sur une seule ligne transporteuse.
