Claims
- 1. A method of making a precision transducer for position measurements, comprising a pair of supports movable relative to each other and each provided with an electric winding constituted by equidistant serially connected printed circuit conductors extending transverse to the direction of relative movement, the winding of one of the supports comprising a plurality of groups of conductors, the condutors of each group being connected in series with each other by auxiliary conductors and intercalated with the conductors of the other group(s), said method comprising the steps of printing the auxiliary conductors on one face of a substrate, bonding the substrate to said support and printing the groups of conductors on the other face after the substrate has been bonded to the support.
- 2. A method according to claim 1, wherein the bonding is effected by interposing a dry cement film between the said one face of the substrate and the said one support and subjecting the resulting sandwich to a given pressure and temperature for a predetermined time.
- 3. A method according to claim 2, wherein the dry cement film is constituted by a thermosetting acrylic resin having a thickness between 0.05 and 0.1 mm, the sandwich being subjected to a pressure between 20 and 30 kg/cm.sup.2 and a temperature between 120.degree. and 170.degree. C. for a time of between 0.5 and 3 hours.
