Documented Quality System

MHCC's highest priority is meeting and exceeding our customers' expectations.  We are committed to consistently manufacturing the highest quality products.  We have a documented quality system that is based on ISO standards.  The procedures are documented in a three-tiered approach:  Level I - the Quality Manual;  Level II - the Standard Operating Procedures detail the  activities necessary to assure conformance to specified requirements; and Level III - detailed Engineering controlled documents identify the individual requirements for manufacturing and inspection of each customers' product.  Each assembly we manufacture is unique and must be built to its own specific requirements.  This allows us to manufacture each assembly consistently within the specifications for each part.

MHCC's products are identified and traceable through all stages of production and delivery.  Individual customer traceability can be maintained, if required, by using unique identification methods for individual products or batches.  All in-process and final product inspections are documented to ensure that customer specifications have been met.  All quality records are maintained to demonstrate achievement of quality requirements and the effectiveness of the quality system.

As a company, we follow:

  • IPC/WHMA-A-620 standards as a baseline
  • IPC-A-620 standards for soldered components
  • MIL-STD-45662A for calibration of test equipment - All tools are traceable to NIST (National Institute of Standards and Technology)
  • ANSI/ASQ Z1.4 Sampling Procedures and Tables for Inspection by Attributes

MHCC also considers employee training and education to be essential in maintaining the high quality of its systems, products and services.  All employees are fully trained and certified according to the quality system.  We empower our employees to provide input to improve their work environment and ultimately the quality of products manufactured.

We are keenly aware that our customers depend on the performance of our products.  To that end, quality and reliability are critical.  We strive on a daily basis to ensure that quality remains an integral part of every function of our company.
