A testing arrangement for a printed circuit board includes a carrier for a multiplicity of contact pins which engage the ends of the printed conductors on the printed circuit board. The carrier is positioned above a base which receives a multiplicity of leads connected with a device for testing the printed circuit board. The leads, which are to be connected with respective ones of the contact pins, engage sockets mounted in the base. The connections between the contact pins and the leads are established via a sheet which is located intermediate the base and the carrier and is provided with contacts in the form of thin foils. The contacts face and engage respective ones of the contact pins. The contacts are connected with plugs which are mounted on the intermediate sheet and are inserted into the sockets in the base. The intermediate sheet is exchangeable and may be replaced either with a sheet having a different pattern of contacts when a new type of printed circuit board is to be tested or with an identical sheet when the contacts on the original sheet become worn. Replacement of the intermediate sheet may be accomplished without disturbing the complicated arrangement of leads to the testing device. |
