Electronic OEMs mostly outsource their printed circuit board assemblies to EMS providers. This helps them reduce their operating costs, and focus on their core business. If you are an OEM, there are chances that you are following the same pattern. As with any other service agreement, you will receive a detailed quote before coordinating with the EMS provider. This post discusses important quote pricing drivers that you need to know about.

12 Important Features of EMS Quotes for Electro-mechanical Assembly Services

The following are some standard features of EMS quotes for electro-mechanical assembly services.

  2. Wave Fixture: This defines the estimated costs for wave soldering. Wave solder pellets are used to mask SMT components, and they protect heat sensitive PCB areas during the wave soldering process.
  3. Warranty and Technical Support: This price is calculated on the basis of warranty liability and technical support for a particular period.

  1. MPI: This price describes the Manufacturing Process Instruction (MPI) development costs.
  2. Set Up Costs: This price is standard across all projects. However, it depends on various factors, such as electricity, repairs, and maintenance, etc.

Before providing the quote, a PCB assembly service provider may ask for detailed BOMs from the OEM, and a set of Gerber files for the PCBs. The BOM defines the approved vendor components, and part numbers for the same. This information will help the service provider determine the packaging, pricing, and availability of each component.
