2、SS-M99P14-A5 PROTECTED EXTERIOR or UNDERHOOD 1. SCOPE This specification defines the performance requirements for pad printing on all Ford Motor Company non class A surfaces located underhood or in protected exterior. Protected exterior is defined as an area where there is very low or no UV exposure
3、. 2. APPLICATION This specification was released originally for pad printing using ink for graphics on globally designed radiator caps. The pad printing process is an ink system which is transferred onto the surface of the part. 2.1 Engineering Drawing Ink supplier and corresponding product codes, c
4、olor codes, and number of hits must be documented on the engineering drawing following the performance specification number. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. All parts must also meet the appropriate DVP & R and Subsystem Desig

6、neering Documents. 3.2.2 Substrate Condition The surface to be pad printed must be cleaned by an automated process to ensure the absence of oil or alkaline residues, fingerprints, corrosion, mold release agents, dirt, moisture, and other foreign materials. 3.2.3 Finished Parts Testing must be conduc
7、ted on actual production parts. Where part dimensions limit equipment access, representative panels run through the production processes may be substituted for production parts. If regrind is used, testing at the maximum loading level is required and must meet the specification requirement. These pa
