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.

Navigating through the complex cable industry can be both difficult and time consuming. This is especially true if, for whatever reason, you have to change your cable assembly manufacturers. This blog post is intended to give you a perspective of what to expect if you find yourself in need of switching an existing cable assembly design to a new supplier.

The old saying “to the victor go the spoils” is now starting to apply in the battery supplier industry. Recently, Panasonic announced that it will no longer be supporting any new battery pack development projects that are not in the electric vehicle (EV) or solar storage space.

Over the course of the last 10 years, e-commerce has gone from something that very few people did to something that is part of our everyday lives. The rise in e-commerce has made many of our lives easier and more productive. The unseen side effect for most people is the strain that this dramatic increase of the “casual shipper” has caused to the existing Air Freight model.
