10. Inspection and testing

prerequisite for making a good product is the use of quality raw materials, technological best practices and good manufacturing documentation. In all parts of the manufacturing process uses proven technology and materials supplied vans perform quality tests. All laminated board passes control to the AOI optical tester electrical tester.

10.1 Checking the input document

10.1.1 Checking the input document when entering the work of the supplied movies

Check the documentation is done from the viewpoint of production. Documentation must meet the needs of technology - are not the customer. Do not, control the technical accuracy of the theme. The film supplied documentation assume no responsibility for any defects contained in the theme connections and differences between the location of drill holes and their diameter in relation to soldering plates on the original film. The scope of control when entering the film documents:

  • full number of films corresponding entry.
  • correct version of the film positive - negative.
  • accuracy of the location of the motifs on the film emulsion.
  • clearly the position of the film on DPS defined nezáměnným alphanumeric character. No clear indication customer may not be such a contract entered into production.
  • Whether or not "drilled" solder pads on the film original. From these patterns produce made-layer PCB.
  • Visual inspection of the undamaged film originals.
  • check sharpness rendered drawings. The check is carried uvšech orders, if the documentation is not stored in our archives and is charged according to the price list.

10.1.2 Checking the input document when entering data in a form.

  • perform a full scan data in terms of manufacturability of PCB including the capture of small defects in the petition. It is all about control drilling programs - removal - double holes or nevrtaných solder surfaces - forgotten hole, centering solder areas to drilling. We catch and remove defects in printing - Print via solder surface. We will observe defects in the theme as isolation distances are small, disproportionately small solder lugs for the prescribed drilling and unlinked - broken connections. This review is from our manufacturing automated macros 350 SW CAM v9.51. This software processes the data supplied to the materials necessary for creating screenplays with regard to production technology and all the recommendations in the TPV.
    • perform minor adjustments to the data needed to render good screenplays. Control drilling data sfilmovou artwork - bore diameter and size of solder lugs spřípadnou editing.
    • Comparison motives skontrolními prints. If you are proofing supplied (preferably by fax or E-mail), the comparison skontrolními prints made technical department. Interventions in the motifs is done only with the consent of the customer. This check is not charged, is part of the preparation of data for drawing screenplays.
    • U multilayer boards and perform general inspection netlist. If Netlist creates illogical projení contact the customer.

    10.2 Inspection and testing

    All manufactured PCB through-process and final inspection and recorded parameters are compared with the established tolerances or with their terms of authority. The actual production process is monitored by the inspection department.

    10.2.1 Inspection and testing work

    control unit provides:

    • written test and review material entering the production
    • inspection and maintenance of spas and solutions used vchemickém and electroplating operations.
    • -destructive and destructive testing and screening products (cuts DPS) and maintain documentation of these tests
    • continuously evaluates the quality of production, negotiate and conclude defects in manufacturing and suggests methods to eliminate them.

    10.2.2-process inspection and testing

    process controls ensures:

    optical completeness check motive for PCB etching on the optical tester AOI ARGOS 8008 Control the conductivity of PCB and two multilayer printed circuit boards for electrical tester companies Mania - Speed ​​Test System MPP 4504th Vroce 2004, we made another very powerful tester Japanese company MicroCraft - EMMA ELX6146. Since December 2007, was put into operation this one machine. Test passes all made plates with a via hole.

    10.2.3 Final inspection and testing

    output control checks vans and piece:

    The delivery control check is made of one piece of the consignment, which examines whether the implementation of PCB corresponds to the customer. Checks the size, type solder masks, prints and other adjustments ordered by the contracting authority, such as the requirement to dovrtání neprokovených holes and profile milling and all these other requirements. Then a check is made piece.

    The routine checks is a visual inspection of all the panels of the van. It focuses on the final surface finish, optically controlled quality plating and surface treatment halováním or gilding and completeness of delivery. U multidesek boards made a re-check on the electrical conductivity tester.
