Contract Design & Manufacturing

How can Dishtronix help you?

We can take your design concept, provide all of the electronic engineering, and provide assembled circuit boards delivered to your factory dock just in time.

We can deliver your production ready boards before you can interview and hire the right engineers and develop the infrastructure and support facilities yourself. We usually can do it at far less cost also.

We can reduce your risk because you don’t have to make a large capitol investment in the infrastructure to support an electronic design and manufacturing group. We know from experience where project pitfalls and common technological mistakes are. We have already made them so you do not have too!

We are familiar with UL and IEC standards and can design your product for the global marketplace. We can arrange and coordinate the necessary tests and approvals.

We have developed specialized testing and design techniques to increase circuit immunity to radiated, suscepted and conducted electromagnetic interference.

We have developed specialized testing and design techniques to reduce the number of field failures that when checked at the factory on return, have “no apparent defect.”

We have developed specialized knowledge and design techniques to increase reliability and lifetime in the areas of:

  • Relays
  • Triacs
  • Electrolytic Capacitors

How can Dishtronix reduce your time to market?

We have a large and varied inventory of components on hand for prototyping our designs. The parts are already input in our CAD and Cost database.

We have heavily invested several man years of time in developing and debugging standard assembly language algorithms for Motorola and MicroChip microcontrollers. Cutting, pasting and splicing different code modules into the framework of our interrupt driven main program structure allows us to get quickly to market. We also offer C based RTOS programs.

A sample listing of our standard libraries include:

  • Multiplexed keypad and LED drive interface routines.
  • LCD / VFD module interface routines.
  • I2C interface to serial EEPROM routines.
  • SPI interface routines.
  • RS-232 and RS-485 interface routines.
  • Measurement and linearization algorithms for temperature (RTDs, thermocouple, PTC, semiconductor), voltage, current, resistance, frequency, A/D converter and PWM.
  • Real Time Clock (RTC) with power line or crystal derived timing accuracy.
  • Zero crossing relay and triac drive routines.
  • Proprietary techniques to reduce power dissipation and prolong critical component life.
  • 8/16/32 bit PID control algorithms.
  • 8/16/32 bit mathematic libraries (addition, subtraction, multiplication, division)


We have heavily invested several man years in the development of MathCad based engineering analysis worksheets for many circuit building blocks, most of which are parametrically categorized and Modeled in PSPICE. A sample of our hardware technology base includes:

  • Motor Controls (Variable Speed):
    • Stepper (full wave chopper or microstepping).
