Avoiding Expensive PCB Materials & Processes

Printed circuit boards are only one component of an enitre assembly designed to meet the best cost-to-performance ratio possible. The finished product into which the PCB is installed must meet a price point that compares favorably against competing products, so the lower the expenses, the more money your product returns. In order to make the best choices during the design cycle, it is important to first understand what drives the primary costs.

Adhesive & Adhesiveless Polyimide Flex Core Material Types

Written by Paul Tome - Product Manager Flex & Rigid Flex
Posted on March 6, 2015 at 1:27 PM

Two distinct types of polyimide flex core material constructions are utilized in today’s flex circuit manufacturing: adhesive based and adhesiveless. The difference, as you can probably tell from the name, is the method used to attach the copper layers to the polyimide core. This creates a unique set of material properties for each of the material types which must be factored into designs to meets all requirements and remain cost effective.

When you consider and evaluate the true stresses that lithium batteries encounter, most battery packs are designed to last three to five years if used and stored properly. Environmental conditions, not just charge cycling, are the key factors for longevity. The worst situation is keeping a fully charged battery at elevated temperatures. When not in use, batteries must be stored in a cool place.

How To Select Your Battery Pack Cell Type

Written by Anton Beck - Battery Product Manager
Posted on October 15, 2014 at 2:03 PM

There are several factors to consider when selecting the type of battery cell to use in your battery pack design. Looking at the battery requirements and the dimensional space available are important. Another factor that comes up is pricing. The top tier manufacturer brands can be expensive, but there are also comparable solutions in Asia that will reduce the cost.

What Is Cable Pre-Molding?

Written by Brian Morissette - Cable Assembly Product Manager
Posted on August 25, 2014 at 2:07 PM

Cable pre-molding, sometimes associated with potting or encapsulation, is used to protect the termination points from the surrounding environment.  Pre-molding involves the application of a material around the back section of a connector where the termination points are located.

What Is The Recommended Copper Weight For A Flex PCB?

Written by Paul Tome - Product Manager Flex & Rigid Flex
Posted on July 18, 2014 at 10:05 AM

The copper weight and corresponding thickness used in a flexible circuit board need to be carefully selected in order to meet both the electrical and mechanical bend requirements of specific flex circuit design. Copper weight for a flex PCB is both the stiffest and most critical component.

The need to protect your keypad from the ever-present threat of wear-and-tear is crucial for all applications.  If your control panel is going to be used in marine environments, medical devices, or other consumer electronics, the threat of water or liquid exposure is ever present. In wet situations, it is critical that all electronic components are completely sealed off from any outside substances that could damage the device.

What is a Flexible Circuit Coverlay?

Written by Paul Tome - Product Manager Flex & Rigid Flex
Posted on March 14, 2014 at 2:45 PM

In the flexible printed circuit board manufacturing process, a flex circuit coverlay (aka coverfilm) is used to encapsulate and protect the external circuitry of a flexible circuit board.

A flexible circuit coverlay serves the exact same function as solder mask that is used on a rigid printed circuit board. The difference with a flex coverlay is the needed element of flexibility and durability it provides to the flexible circuit board.

Why Use A PCB Membrane Switch Combination?

Written by Epec Engineered Technologies
Posted on March 3, 2014 at 12:33 PM

Many applications would be better suited using a membrane switch (low profile, flat surface keypad assembly) along with a rigid printed circuit board (PCB), replacing screen-printed silver conductors on polyester sheets.

Printed circuit boards with gold plated switch contact pads and gold plated dome switches greatly improve the reliability of your application, offering longer operating life with lower switch resistance and contact bounce.
