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.
One question we get asked frequently is: "Why does flex and rigid-flex PCB tooling cost more than rigid PCBs?" The answer is quite simple; flex circuit tooling is a much more complex process than standard printed circuit boards.
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.
We’ve received cable requests on a hand-drawn dinner napkin, 8x11 pieces of paper, and even old pictures. Regardless of the format, once the request is received it is drawn into a basic design which is sent to our Engineering team. We need to have the requested design in a particular format in order to be able to manufacture the request appropriately. Otherwise, our facility would not be able to understand dimensions (etc.) correctly. An official manufacturing ready design drawing would then be returned to you.
