Writing an Assembly Folder – detailing the guidelines required for the process…

  • Defining a standard for assembly work – IPC610 CLASS 2/3.
  • Definition of an FAI (FIRST ARTICLE INSPECTION) process.
  • Type of paste – LEAD FREE, LEADED according to the types of components and PCB and depending on lacquer coating requirements.
  • Type, thickness and size of the tin print mask according to the components type and size of the PCB / panel – staggered masks.
  • Order of components assembly on CS / PS.
  • The desired temperature profile for the selected types of components.
  • Defining the equipment required for optimal performance of the assembly.
  • Components requiring early drying (MSL3).
  • Components that require X-RAY testing.
  • Manual completion and soldering.
  • Topics raised as exceptional during the PCB design stage
  • Visual testing during the process and at the final stage (AOI).
  • Specific guidelines for performing full integration of the product according to the product and end customer requirements.
  • Guidelines for electrical testing of the circuit and/or the product based on customer requirements.
  • Guidelines for writing and filling accompanying tags to ensure full traceability of the
  • PCB/final product.
  • Guidelines for packing and transporting the PCB/product.

Surveying and locating an assembly subcontractor, compatible with the needs of the project

  • Knowledge of the subcontractors market and the existing capabilities in accordance with the product and customer requirements.
  • Selecting the suitable subcontractor for the assembly of the type of complexity embedded in the PCB – the types of components and technology requirements versus equipment type existing in the company.
  • Marel will perform full matching between the product design and the requirements derived from it and the capabilities of the circuit board assembly subcontractor in order to prevent failures.
  • Performing survey of new companies based on customer/product requirements and preparing a summary report.

Accompanying the assembly of the PCB at the subcontractor’s site

  • Presence and full support of the assembly process at the subcontractor’s – responsibility for the execution of all guidelines.
  • Control the quality and performance schedule as determined with the client.
  • Producing a final report including NPI, X-ray photographs and providing a report regarding the quality of work/PCB/product.
