An electronic, digital IC module includes a substrate element on which is formed a test integrated circuit for the execution of a boundary scan on a standard integrated circuit formed on another substrate element. Either the substrate for the test circuit is provided in an electronic sub-module on which is formed a test socket, in which case the standard circuit is mounted piggy-back, or a hybrid package is provided composed of the two substrate elements which are interconnected by bond pads. The test circuit includes a shift register for parallel connection to the standard circuit and serial connection to an external test unit.

Electronic module comprising a first substrate element with a functional

A cathode ray tube electromagnetic deflection unit comprising field deflection coils (8,8') and line deflection coils (10, 10'), both of the saddle type, wound directly onto an annular support (4). The field deflection coils consist of a first part (11) wound against the inner side of the support (4) and a second part (12) wound against the line deflection coils (10, 10'). At the narrow end (5) of the support (4) the second part (12) extends in the longitudinal direction further than the line deflection coils (10,10'), and the first and second parts (11, 12) are electrically connected in series. Such a deflection unit has high sensitivity and minimizes coma errors.

Electomagnetic deflection unit

An electromagnetic deflection unit for a cathode ray tube, comprising has at least one support (4) with a flange (8) at its narrow end (5), which has a tangential groove into which merge radial grooves (14). Two sets of deflection coils (18, 19) are wound directly onto the support (4). The turns thereof traverse the radial grooves (14), the turns of at least one set of deflection coils (18) being bent into the tangential groove. The radial grooves (14) have longitudinally extending portions (16), which are filled by the turns traversing them. The bottom portion (20) of the tangential grooves lie on the surface of an oval cylinder. The deflection unit has a high sensitivity, large axial sliding tolerance and permits correction of various kinds of deflection errors.
