CCM - WHO WE ARE
Over 20 years ago, Coto Contract Manufacturing’s parent company (Coto Technology) opened its highly-successful Mexicali, Mexico facility.
Located only 2-1/2 hours from San Diego, California, Mexicali is where many of Coto Technology’s products are now engineered, manufactured, assembled and tested.
Today, Coto Technology is branching out to make its well-developed resources available to strategic partners under the division, Coto Contract Manufacturing or “CCM”.
CCM offers its physical resources as well as experienced engineering support, knowledgeable product development experience, and a highly-skilled work force to provide a wide range of hand assembly processes.
Customers of CCM benefit from our existing automated winding, molding and forming machines which promote precision operations with high productivity.
Since Coto Technology specializes in the manufacture of relays, switches and sensors, our existing technologies include coil winding, conventional molding, transfer over-molding, and injection molding.
Mexicali is home to six universities and 12 technical trade schools. Inhabited by nearly one million people, there are 180,000 workers with skills ranging from basic manpower to highly specialized professionals. Couple that with advanced communication systems and an integrated transportation network by air, land and sea, and Mexicali is a mecca for high tech industry.
OUR PARENT COMPANY – COTO TECHNOLOGY
Coto Technology is the worldwide leader of small signal switching products sold into the Automatic Test Equipment, Data Acquisition, Instrumentation, Process Control, Telecommunications, Medical and Security markets.
Coto Technology’s relay design labs and corporate offices are located in scenic North Kingstown, RI (USA) along the shores of Narragansett Bay.
From coil windings and reed relays to dry reed switches and MEMS-based sensors, Coto has established itself as a market leader in product quality and design innovation.
Coto Technology’s reed relay & reed switch manufacturing facility is located in Mexicali, Mexico.
Coto Technology, Inc. originated in Providence, Rhode Island, USA in 1917 as Coto Coil Incorporated - a company specializing in the design and manufacture of coil windings. During the mid-1960’s, Coto expanded its product line by introducing the reed relay - the result of integrating reed switches into coil windings. By 1970, Coto emerged as a leading manufacturer of reed relays with the development of the first patented Low-Thermal EMF reed relay. Coto went on to produce the first ever surface mounted reed relays in 1983, the world’s smallest SMD reed relay in 1994, and the first patented reed relay with >8 GHz performance in 2001.
In 2010, Coto relocated its relay design labs and corporate offices to scenic North Kingstown, RI along the shores of Narragansett Bay. The new, high-efficiency facilities allow Coto engineers to focus on developing solutions for tomorrow’s small signal switching applications. Whether it’s high-speed serial data communication, signal integrity analysis, or the increasing demands for greater bandwidth and higher frequency, Coto is prepared and committed to solving the applications concerns of our customers now and in the years to come. In 2014, the company introduced its comprehensive CotoMOS® solid state relay line.
Today, Coto is a worldwide market leader of small signal switching products sold into the Automatic Test Equipment, Data Acquisition, Instrumentation, Process Control, Telecommunications, Medical and Security markets.
Coto specializes in the manufacture of relay and switch products. Non-standard package sizes and pinouts, custom coil and shielding designs, and multi-pole configurations are common variables. Coto relays are capable of carrying up to six amps, and can provide switching currents up to four amps along with 10-15 KV switching.
Coto relays are qualified to the highest electrical test specifications in the reed relay industry.
To improve efficiency, enhance responsiveness and increase capacity, Coto has renovated its manufacturing facility in Mexico by investing in additional manufacturing automation technology. Manufacturing processes utilizing ergonomic workstations, coupled with fully automated winding, wire termination, molding and laser marking increase efficiency while ensuring high levels of quality. Also, a Learning Center provides Coto employees with educational opportunities, enhancement of job skills, and operator certification.
TOTAL QUALITY MANAGEMENT
From the production line to the executive office of the company President, Coto’s commitment to quality is evident - as manifested by its world class products. Coto is certified to ISO-9001:2008. Additionally, Coto’s environmental policy and controls are compliant with internationally accepted standard manufacturing practices aimed at reducing the effect of manufacturing activities on the environment. All Coto standard products have transitioned to RoHS compliant versions.
Coto operates in an environment of structured problem solving, using cross-functional teams for product development planning and continuous improvement processes. These team efforts combined with active customer involvement ensure product designs that meet or exceed customer needs. Continuous production monitoring is accomplished through the use of Statistical Process Control (SPC) and other quality practices such as FMEA’s (failure mode and effect analysis), PPAP’s (production part approval process) and zero acceptance sampling are used for analysis and monitoring of key parameters. Coto’s quality philosophy and discipline provide the building blocks for its reputation as the world leader in quality small signal switching products.
Coto has the most advanced testing capability of any reed relay manufacturer. After the relays have been assembled, assurance of their conformity to specifications is accomplished through 100% testing.
Coto tests relays to the highest standards in the industry using its proprietary “System 320” Parametric Tester. The System 320 is capable of testing over 20 different parameters of the relay and recording the results of each test for each relay. This information can be retrieved in the form of Histogram graphs, Individual Results reports or Pareto Failure Analysis reports.
Results from the test systems are networked in real time, allowing immediate access to statistical data on product performance and quality. Coto emphasizes Pareto-style graphical ranking of yield data, allowing for quick identification and resolution of problem areas. This aids the analysis of the relay’s performance over time and continuous quality improvement.
Throughout the manufacture of Coto switches, a zero failure acceptance testing system is used for each critical process step.
The mechanical and chemical properties of the switches after process stages such as plating, diffusion, sputtering, sealing and forming are inspected to ensure conformance to required specifications. Prior to shipment, 100% of the switches produced are electrically checked for AT value and contact resistance.
Our life testing laboratories can cycle relays or switches while applying a wide range of load voltages and currents.
Relays are concurrently tested up to one billion cycles. The effects of surge currents from reactive loads can be included. Failure data is analyzed using Weibull techniques to allow accurate prediction of MCBF (mean cycles before failure), and the confidence limits that apply. Coto also has a sweep frequency life tester designed to probe reed switch blade resonance and its effect on long term contact resistance.
More advanced tests include Paschen voltage breakdown to detect switch seal breakdown, and an automated tester designed to determine the contact welding resistance of reed switches. Coto is also equipped with high-end digital oscilloscopes and network analyzers, to meet the increasing demand for relays with RF bandpass above 10 GHz.
Coto also maintains a highly-capable failure analysis laboratory that performs electrical testing, cross sectioning, x-ray, chemical and microscopic inspection, helium leak test and element analysis.
Finally, Coto has a robust organizational structure with a highly skilled and qualified staff in all job functions. The company continuously promotes the development of its employees through well-defined training and certification programs.
Coto is an ISO-9001 certified company. Our facilities comply with ESD and all pertinent safety and environmental regulations. Our product portfolio meets RoHS international standard and product safety agency approvals from UL and CSA. Additionally, Coto is dedicated to promoting the principles of Lean Six Sigma - a disciplined, data-driven approach and methodology for eliminating defects and systematically removing waste.
