Contract electronics manufacturing service or Orange County EMS companies normally deal with clients in a large range of markets with varying demands for stock control, screening, item packaging, and product support. In some applications, the EMS provider simply puts together the printed circuit boards and then ships the boards to the consumer. In other applications, the EMS provider will certainly put together the printed circuit board, load firmware/software into memory, test the board, then assemble the board and associated cable televisions, enclosures, and documents into a finished item that is shipped to the client. Some consumers will certainly offer all the materials, raw boards and electronic elements, required for a job and the EMS company assemblies the printed circuit boards, performs any required testing, and ships the completed boards to the customer.
Some clients offer some portion on the products, such as specialized or high expense incorporated circuits, proprietary parts such as transformers or coils, raw printed circuit boards, etc. and rely on the EMS company to buy the rest of the components needed to assemble the boards. Many EMS companies prefer to utilize their own purchasing power, their comprehensive contacts, and their existing parts stock where applicable to offer all of the necessary products for a client’s particular job.
Prior to any of this can take place, the EMS carrier have to offer an assembled board quote or pricing quote to the consumer for the project. In addition to the amount commitments, production release amount and annual use amount, this pricing process also needs an in-depth bill of product from the consumer together with a set of the Gerber apply for the printed circuit boards. The BOM must specify all the parts in addition to the authorized vendor and supplier’s part number for each component. This info permits the Materials Management group to identify accessibility, product packaging, and rates for each part based on the amounts and supplier information. The BOM information is also had to permit a technical evaluation to figure out the quantity of labor and the equipment needed to put the parts and to solder the components to the board.
The Gerber files for the printed circuit board design offer Materials Management with the information they need in order to get raw board pricing and lead times from the printed circuit board producing suppliers. In order to properly place elements on the printed circuit board with each element properly oriented, the EMS company will require silkscreen files to know the right orientation of the parts on each side of the board.
All of this might appear to be a lot of info, but each piece is needed in order to offer the most cost efficient pricing for the finished item. Aid your EMS service provider by offering the approved supplier’s name and part number for each element.
In other applications, the EMS provider will certainly assemble the printed circuit board, load firmware/software into memory, test the board, and then assemble the board and connected cables, enclosures, and paperwork into a completed product that is delivered to the consumer. Some clients will certainly supply all of the products, raw boards and electronic elements, needed for a job and the EMS company assemblies the printed circuit boards, carries out any required testing, and ships the completed boards to the consumer.
Some consumers supply some part on the materials, such as specialized or high expense incorporated circuits, exclusive parts such as transformers or coils, raw printed circuit boards, etc. and rely on the EMS company to purchase the rest of the elements required to put together the boards. The Gerber files for the printed circuit board design provide Materials Management with the details they require in order to get raw board rates and lead times from the printed circuit board manufacturing vendors.
