3、2 ELECTRICALLY HEATED BACKLITE, POLYCARBONATE 1. SCOPE These specifications define the performance requirements for a heated backlite comprised of conductive materials either fired and fused to float glass, or thermally cured materials which are printed or applied onto polycarbonate glazing systems.

4、 2. APPLICATION These specifications were released originally to supplement information on the engineering drawing for an electrically heated backlite assembly for defroster and/or defogger purposes. In addition to the requirements listed in this specification, requirements listed in the SDS must be

5、 met, unless otherwise agreed to by Ford engineering 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Unless otherwise indicated on the engineering dr

6、awing, the following requirements are applicable to full size backlite or suitable size test specimens, prepared concurrently with the backlites. The size of the test specimens used, shall be governed by the test conditions. All test plaques must go through process conditions identical to that of fi

There shall be no skips or breaks in the conductors detectable by visual or electrical means

11、which would affect the normal functioning of a heated glass or polycarbonate backlite. 3.7 THERMAL SHOCK ADHESION There shall be no loss of adhesion or continuity between the conductors and the backlite, when an assembly is subjected to 4 cycles. These requirements supplement information appearing o

12、n engineering drawings and engineering specifications for Electrically Heated Backlites containing fused silver filled ceramic or non-ceramic conductors. Test Method: The backlite shall be placed in a cold box at -40 +/- 2 C for a period of 2 h. On removal from the cold box, the backlite shall be pl

13、aced immediately in an oven at 82 +/- 2 C for a period of 2 h. 3.8 WEATHERING RESISTANCE After exposure in accordance with 3.8.1, material shall show no color change in excess of specified Grey Scale rating (AATCC Evaluation Procedure 1/ISO 105-A02). In addition, there shall be no cracking, crazing

GENERAL INFORMAT

21、ION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 CLEANING Glazing surface must be free of dirt, oil, fingerprints and any other material which would interfere with the adhesion or functioning of the silver-ceramic con

22、ductors. Highly abrasive materials and/or sharp instruments that would damage the conductors should be avoided when cleaning the interior surface of the backlite assembly. 5.2 FIRING SCHEDULE (For glass only) The firing cycle normally used to fuse the silver-ceramic conductors shall be equivalent to the production curing and temperature cycle. 5.3 CURING SCHEDULE (Polycarbonate System) The curing cycle for printed conductors shall be equivalent to the production curing and temperature cycle.
