Electronics Manufacturing Service
Contract electronics manufacturing service or EMS providers typically work with customers in a wide range of industries with differing requirements for inventory control, testing, product packaging, and product support. In some applications, the EMS provider simply assembles the printed circuit boards and then ships the boards to the customer. In other applications, the EMS provider will assemble the printed circuit board, load firmware/software into memory, test the board, and then assemble the board and associated cables, enclosures, and documentation into a finished product that is shipped to the customer. Some customers will provide all of the materials, raw boards and electronic components, required for a job and the EMS provider assemblies the printed circuit boards, performs any required testing, and ships the finished boards to the customer. This is generally considered as inventory provided on a consignment basis where the EMS provider basically provides labor and expertise only. Some customers provide some portion on the materials, such as specialty or high cost integrated circuits, proprietary parts such as transformers or coils, raw printed circuit boards, etc. and rely on the EMS provider to purchase the remainder of the components needed to assemble the boards. Most EMS providers prefer to use their own purchasing power, their extensive contacts, and their existing parts inventory where applicable to provide all of the required materials for a customer's particular project. This method is generally considered as inventory provided on a turn-key basis.
But before any of this can happen, the EMS provider must provide an assembled board quote or pricing estimate to the customer for the project. In addition to the quantity commitments, production release quantity and annual usage quantity, this pricing process also requires a detailed bill of material from the customer along with a set of the Gerber files for the printed circuit boards. The BOM should define all of the components along with the approved vendor and vendor's part number for each component. This information allows the Materials Management group to determine availability, packaging, and pricing for each component based on the quantities and vendor information. The BOM information is also needed to allow a technical review to determine the amount of labor and the equipment required to place the parts and to solder the components to the board.
The Gerber files for the printed circuit board design provide Materials Management with the information they need in order to get raw board pricing and lead times from the printed circuit board manufacturing vendors. The Gerber files also provide the Manufacturing Group with the information they need to develop the manufacturing plan, are components on top only or top and bottom of board; surface mount, thru hole, or mixed component types; wave solder or reflow oven processes required, etc. The Manufacturing Group also has to estimate time to program the component placement equipment and to load the components in the placement feeders, set-up costs, costs to order the solder paste stencils, and must also quantify test plans, procedures, and required test equipment. In order to correctly place components on the printed circuit board with each component properly oriented, the EMS provider will need silkscreen files to know the correct orientation of the parts on each side of the board. The screen paste file for surface mount applications will be required to order the stencils for the solder paste application to the board prior to the part placements.

The EM1 is a transmissive optical encoder module. This module is designed to detect rotary or linear position when used together
with a codewheel or linear strip. The EM1 consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer
package.
The EM1 uses phased array detector technology to provide superior performance and greater tolerances over traditional
aperture mask type encoders.
The EM1 module provides digital quadrature outputs. A third index channel output comes standard on all resolutions. Power is
supplied from a single +5Vdc source. The single-ended outputs are capable of sinking or sourcing 8mA each.
The resolution of the modules and encoder disks or linear strips must match. Two mounting holes are provided to accept #4-40
machine screws. Because there is clearance in these mounting holes they should not be relied upon for accurate positioning;
instead, mounting assemblies should incorporate two alignment pins (nominal diameter 0.095") just in-board of the mounting holes
(see drawing).
For open collector and higher voltage applications, add the PC3 cable driver, or for differential cable driver outputs, add the PC4
cable driver. Encoder disks, linear strips, quadrature decoder chips, counter chips, computer interface boards, mating connectors
and cables are also available.
