Cable Harness Assembly

ACME PCB Assembly Offers Cable Harness Services

Cable Assemblies include one or more wires that run together in a single sleeve with a connector or plug on each end.  Cable assemblies could be groups of wires or cables bundled together.  They are wrapped in a thermoplastic or vinyl sleeve, cable assemblies are ideal for directing groups of wires and cables around obstacles.

Cable assemblies are designed to perform specific functions that is determined by the plugs, terminals, and connectors that are found on each end.  They are used in most electronic applications, everything from flat panel displays to the automotive electronic system to integrated cockpit systems to simple LED lighted clothing, costumes and accessories.

What Do You Use Cable Assemblies For?

Cable assemblies intersect or interconnect different circuits or electrical paths, so they work together to transmit signals or power.  They usually only have two ends to connect point A to point B.

Ethernet Cable HarnessFor example, ethernet cable assemblies are designed to provide service supporting bandwidth speeds up to 10 Gigabit Ethernet, such as large data centers, military field units, and medical facilities.  For those applications that require a lightweight, smaller assembly that can transmit clearly and rapidly over great distances, support greater bandwidths, with high voltage isolation, then fiber optic cable assemblies would meet those needs.  A few of the industries that utilize fiber optic cable assemblies, include aerospace, automotive, industrial, medical, and military applications.

Cable harnesses are more complex in nature and may require different machinery and tools to be consistent with production. Creating slits and windows in cables demand specialized equipment to handle the various conductors within the insulation.  We

Why Consider Using Through Hole Printed Circuit Boards?

Why Consider Using Through Hole Printed Circuit Boards?

In the printed circuit board business, there are two primary ways to mount components onto the circuit board: through-hole mounting and surface mounting. Through-hole mounting is the older technology and requires the circuit board manufacturer to drill holes through the PCB and place leads into the holes. More recently, surface mounted technology has taken over the field.

Through-Hole Components

Through-hole components come in one of two types of leads, radial and axial. Axial through-hole components run along the axis of symmetry of the component while radial components protrude in parallel from the same surface on a board.

Components of Surface Mount Technology

When you look at any modern PCB design, you will see SMT technology in most instances. Surface mount technology (SMT) is the most commonly used technology today. These types of boards and components have very small or no leads at all as their primary purpose is to be soldered directly on the surface of a PCB during the design process. This method allows for components to be much smaller, allowing for greater density and better overall performance on a smaller circuit board.

With surface mounting offering so many benefits, why even consider through hole flex printed circuit boards?

The reason is that through hole mounting offers stronger mechanical bonds. This makes through hole flex printed circuit boards the better option for devices that are designed to undergo major stresses, like sudden accelerations, collisions, or extreme temperatures. This makes them worth considering for military, automotive, and extreme sports applications.

How you Would Create an Electronic Prototype

How to Create an Electronic Prototype

Do you have a big idea for a new electronic product? We all know that ideas are a dime a dozen, so if you really want to get your idea off the ground, eventually you’ll need to create a prototype. A prototype, simply put, is a physical manifestation of a product. There are many important reasons to create a prototype. In this article, we’ll also review some quick tips about how to turn your idea into a prototype.

Why Prototype?

Creating a prototype is an essential step in your journey to bring your product to market. One of the biggest reasons to create a prototype is to simply work out all the bugs and kinks. Designing the prototype will help you determine if you’ve got the size right, if it can really work as you’ve imagined, and what the best materials are.

A prototype is also practically a requirement if you’re looking for seed money. No investor is going to write you a check if you aren’t at least serious enough to show them an early model of your product.

How to Create a Prototype

prototype-assembly-YUN-INDUSTRIAL-1

A prototype starts with a drawing. You can take an actual pen to paper for this step, but eventually it’s a good idea to either create or commission a CAD drawing (computer-aided design), which will provide greater detail and accuracy.

Next, you may want to try and build a preliminary prototype of y our product just to test out the dimensions and see what it will look like. This will not be a working prototype. If you are handy, you may be able to fashion it yourself using foam, moldable plastic, metal, wood, or parts from other products.

Eventually, though, you’ll want to create a working prototype. This will be important to showcase to investors. Since you are creating an electronic product, it is likely that you’ll want to work with professional prototype developers. These are manufacturers who specialize in developing prototypes. They are experienced in helping entrepreneurs and inventors just like you figure out how to actually create the prototype. For example, they can help you determine the right materials and figure out how the actual product will work.

At Yun Industrial Acme PCB Assembly, we can help you create your electronic prototype. Send us your CAD drawing and other paperwork, and let’s get started on building your product!

Conformal Coating Spray

The Growing Importance of Conformal Coating in PCB Protection

Printed Circuit Boards (PCBs) are at the heart of modern electronics—but as devices become smaller, more powerful, and more widely used in harsh environments, protecting these sensitive components has become more critical than ever. That’s where conformal coating in PCB protection steps in as a game-changer.

Whether it’s a consumer product exposed to daily wear or a military-grade device deployed in extreme climates, PCBs need an added layer of protection. Conformal coating provides exactly that: a thin, durable film that safeguards electronics from moisture, dust, chemicals, and temperature extremes without compromising performance or size.

Solder Mask on Printed Circuit BoardsWhat Is Conformal Coating?

conformal coating maskingconformal coating maskingConformal coating is a protective chemical layer applied to the surface of a PCB to create a barrier against environmental contaminants. It’s “conformal” because it conforms to the shape of the board and its components, coating even hard-to-reach areas without needing bulky enclosures.

At Board Assembly, we apply conformal coatings using precise, industry-approved techniques that ensure full coverage without interfering with the function or accessibility of electronic parts.

Why Is Conformal Coating Becoming More Important?

As electronics continue to expand into sectors like automotive, aerospace, defense, and IoT devices, the environments these PCBs operate in are becoming more unpredictable and challenging.

Here are a few key reasons conformal coating is gaining traction:

  • Moisture & Corrosion Resistance: In humid or marine environments, moisture can cause corrosion, short-circuits, and long-term failure. Conformal coatings seal off the PCB surface, keeping moisture at bay.

  • Chemical Protection: In industrial settings, exposure to cleaning agents, fuels, or harsh chemicals is common. A conformal coating acts as a shield, preventing chemical damage.

  • Dust & Debris Protection: For electronics in outdoor or manufacturing environments, dust accumulation can hinder performance. Coatings protect against particulate buildup.

  • Extended Product Life: By protecting the PCB from environmental damage, conformal coatings significantly increase product reliability and longevity—essential for industries where equipment failure is not an option.

Applications Across Industries

From automotive control units to aerospace avionics, and from wearable medical devices to outdoor smart home systems, conformal coating in PCB protection is now a standard best practice in many industries. As miniaturization and high-performance demands increase, protective coatings are no longer optional—they’re essential.
