Defining and providing guidelines for planning and building a library of components depending on the DFX method

Planning components structure (PCB FOOTPRINT) optimally, which includes:

  • Desirable contacts size.
  • Optimum size openings for solder paste printing.
  • Defining the optimum solder mask opening for the component.
  • Definition of maximum size for the component (boundary).
  • Optimal design of the component silk.
  • Component height definitions for the purpose of modeling IDF versus mechanical design.

Guidelines for the PCB designer for working according to manufacturing and assembly considerations in DFX methodology.

  • Mechanical designer guidelines regarding the manner and form of materials submission for PCB design.
  • Definition of responsibilities allocation among PCB designer – mechanical designer – MAREL company.
  • Circuit design for manufacturability – DFM.
  • Circuit design for assemblability – DFA.
  • Circuit design for testability – DFT.
  • Planning and adjustment of layers structure, with proven production capability according to customer requirements and the electronic / electrical needs.
  • Definition of distances between conductors, between conductor and surface, conductor to hole, etc., in the internal / external layers, depending on the selected layers structure.
  • Planning and adjusting of types of drilling (stacked vs staggered via, blind via, buried via) to the requirements of the product / customer versus cost.
  • Planning and adjustment of the layer structure to the process of filling holes with epoxy / copper to increase the durability of the structure according to the defined environmental conditions.
  • Designing optimal distances between components, normally and / or for rework depending on the selected types of components.
  • Shape, size and optimal location of the fiducial points (FID) in order to obtain the best result of assembly quality.
  • Optimal panelization design in terms of maximum utilization of raw materials, requirements for assemblability and testability.
  • Planning separation of PCB from the panel depending on mechanical design constraints.
  • Definition of structure and contents of the files required for manufacturing and assembly.

Design reviews using DR, PDR, CDR management methodology

  • Performance of DR survey with the participation of: hardware / RF development of the client, mechanical designer, PCB designer and MAREL company, in accordance with a systematic and written method.
  • DR survey summary and distribution among the participants, for monitoring project management.
  • Performance of a PDR survey after having reviewed the placement phase (components positioning) with the participation of all participants of the DR in accordance with the topics and an organized and written method.
  • PDR survey summary and distribution among the participants for monitoring project management.
  • Performance of a CDR survey after the routing phase (conductors routing) with the participation of all participants in the DR in accordance with the topics and an organized and written method.
  • CDR survey summary and distribution to the participants for monitoring project management.
  • Production portfolio approval before it is sent to the appropriate manufacturer.

Reviewing and locating the PCB designer according to PCB complexity

  • Knowledge of PCB designers market in Israel and their ability to design circuits according to the required complexity level.
  • The PCB design world is an “arena for major players” and there must be a match between the design capabilities and the continuously increasing requirements.
  • MAREL performs a complete adaptation between product design and the requirements thereunder and the PCB manufacturer capabilities in order to prevent failures.
  • Performance of new companies survey based on customer requirements / product and producing a summary report.
