All companies judge themselves on simple things like revenue, expenses, and income. Most manufacturing companies measure even more metrics like capacity utilization, yield, inventory turns, and on-time delivery. All of which are very important to ensure that business is profitable.

In the world of flexible circuit boards, stiffeners are a common requirement in a lot of flex designs. By definition, a circuit board stiffener provides a mechanical support function and is not part of the electrical schematic of a design.

Today, there are well over 3,000 companies that manufacturer printed circuit boards (PCB) in Asia (China, Taiwan, Japan, India, Korea, Thailand) with the supply capacity continuing to grow well ahead of the global demand.

It is critical for any flex circuit design to be free of errors and violations in order to get the application to market as fast as possible without unnecessary delay. To help designers avoid common IPC PCB design standards violations in rigid-flex PCBs, this blog post will discuss three of the most common IPC Association Connecting Electronics Industries design violations.

A common question in PCB development is why flex and rigid-flex PCB tooling costs more than rigid-only circuit boards. The primary reason is process complexity. Flex circuit tooling involves more fabrication steps, tighter coordination between materials, and a higher level of hands-on engineering compared to standard rigid PCBs.

In addition to fabrication complexity, flex and rigid-flex PCB designs require more engineering programs to be manually created. Many of these steps cannot be fully automated, which increases setup time and engineering labor during the tooling phase.

We find that return merchandise authorizations (RMAs) are a powerful statement of a customer’s level of dissatisfaction. RMAs can offer evidence if a manufacturing process fell short of its goal, there was a lack of communication throughout processes, or even misdiagnosed a problem. In any case, we stand behind our product and are ready to support our customer.

When dealing with requests for custom manufactured custom assemblies, the question that frequently comes up is, "why should a jacketed cable be used in an assembly?" The answer to that question can be determined by looking at three key areas: environment, safety, and cosmetics.

Early on in the printed circuit board (PCB) industry, "quick turn PCB" was a very relative term. Purchase orders were faxed, confirmed with a phone call, and lead time was open for discussion. Quick turn PCBswere 7-10 days, maybe as low as 5-days for a fast PCB manufacturer. A 2-day PCB quick turn was a very rare order which designated a person to move through production from process to process, bumping every other board from the line.

Manufacturing cable assemblies used in precision medical device applications requires rigorous demands just to meet the industry standard. When dealing with these specific applications, failure is not an option. Envision applications used in a medical environment. You must limit the possibility of failure for users in the field. Even something as mundane as cable sterilization can potentially cause the cable to fail and/or cause issues for the user(s).

Hot Air Solder Leveling (HASL) has always been the main staple of PCB surface finishes. In the late 1980s, 60/40 tin-lead reflow started to phase out of processes and was replaced with Hot Air Solder Leveling. HASL finish, the long running reliable surface finish, is still used today in military, aerospace, medical, and other applications.
