CASE STUDY:

Redundant Capacitor Assembly

CAPACITOR MODULE

CHALLENGE: 

  • Tantalum Capacitors were a single point of failure in critical weapons system
  • Replacement and field failures are extremely expensive


SOLUTION:

  • ISI solution provided two capacitors in series, providing redundancy if one cap shorts
  • Unique approach allowed twin capacitor module to be placed on SMT footprint of original single capacitor
  • Design and packaging of module compatible with standard SMT placement equipment

Core Capabilities:

Ruggedization

Custom Interconnect

Manufacturing Tooling

ISI's Co-Development Process

Working with the ISI team is a highly collaborative engagement. The initial requirements customers bring are the starting point, but the big benefit comes as our engineers work to propose various solutions, including pros and cons of each. Those solutions include what many competitors can’t offer, which is in-house execution of nearly all aspects of the project.

Exchange technical details with customer to define challenges and establish scope of the project. 

Assess likelihood of achieving the desired outcome and estimate the required engineering effort.

A quote will be issued to include NRE charges, price for prototypes and production volumes, and timeline for completion.

Design work begins with a particular focus on manufacturability. Frequent technical exchanges with the customer ensure a design that meets their expectations.

Upon customer approval, ISI initiates orders with suppliers and starts developing tools, molds, fixtures, and other custom equipment as required.

After satisfactory prototype testing and customer approval, product is released for volume production.
