Cable Harness Assembly

Our Cable and Wire Harness Assembly Services

Cable Harnesses (Wire harness, cable assembly, wiring assembly) is an assembly of electrical cables or wires which transmit signals or electrical power. Cable harnesses are different from wire harnesses and it is important to understand the difference. A wire is a single conductor, while cables are two or more wires that are insulated being wrapped in a larger jacket. These two technologies demand their own set of unique tools, fixtures, and machinery to help reduce production costs. Knowing exactly what type of product being used is crucial to perfectly create your designs.

·         Wire harnesses generally do not need much to work with and is generally an inexpensive and cost-efficient way for many people to solve their electrical needs. With a single machine, one can increase their production capabilities because of the relative simplicity of wires in general.

·         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

Both technologies are held to the standards like IPC WHMA-A-620 and should be evaluated by their designated class level.

Printed Circuit Board Manufacturing vs. PCB Assembly: Understanding the Difference

There Are Differences Between Printed Circuit Board Manufacturing and Printed Circuit Board Assembly, But You Might Be Asking What Are They?

In the world of electronics, the terms Printed Circuit Board (PCB) Manufacturing and PCB Assembly are often used interchangeably—but they actually refer to two distinct processes. Understanding the difference is essential when choosing the right partner for your electronic product development.

At Yun Industrial / ACME PCB Assembly, we specialize in both PCB manufacturing and assembly services, ensuring customers receive complete, end-to-end solutions with unmatched quality and precision.

What Is PCB Manufacturing?

PCB manufacturing is the process of creating the physical printed circuit board from scratch. This involves several intricate steps, including:

  • Designing the board layout using CAD software

  • Creating a PCB prototype to test design accuracy

  • Layering copper and insulating materials to form conductive paths

  • Etching, drilling, and plating to create traces and vias

  • Applying solder masks and silkscreens for protection and labeling

Essentially, PCB manufacturing is about producing the bare board—the foundation that will later hold the electronic components. This stage requires high-precision machinery and engineering expertise to ensure the final board meets performance, safety, and durability standards.

What Is PCB Assembly?

Once the bare board is manufactured, the next step is PCB assembly (PCBA). This is where the circuit board comes to life. The process involves soldering electronic components—such as resistors, capacitors, IC chips, and connectors—onto the PCB according to the design specifications.

PCB assembly can use Surface Mount Technology (SMT), Through-Hole Technology (THT), or a combination of both, depending on the application. This stage requires precise placement, temperature control, and soldering quality to ensure reliable electrical connections and functionality.

Flexible Circuit board

An Overview of Constantan in Flexible Circuit Boards

The electrical and thermal conductivity that copper creates makes it an obvious choice as a conductor in printed circuit board (PCB) construction, but in many applications that require flexible circuit boards, copper alloy metals can be far better to use. Some of those applications include using conditions of extreme heat or cold, where copper’s low resistance becomes a liability. Constantan is an alloy consisting of 55% copper and 45% nickel, this is one of several metals that has been proven effective for its higher resistance and lower thermal conductivity. Constantan used in flexible PCBs is an ideal choice for many applications.

Flexible circuit

Constantan is the oldest and most commonly used of what are known as “strain gauge alloys,” which are metals used to measure how materials react to stress from various forces. These alloys have become very important to the construction of many flexible circuits. Flex circuit boards are often designed for technologies that operate in harsh environments and require a high density of circuitry in enclosures with limited space. The market demand for flex PCBs that can withstand high temperatures has increased as such components are routinely used in oil drilling, semiconductor processing, medical diagnostic technology, and the construction of airplanes and defense systems.

Flexible circuits are small and light when compared with rigid PCBs and cable bundles. Flex circuits fit into many tight spaces, they can also bend around corners, and can better withstand vibration, high pressure, and extreme temperatures. They take up 75% less space than rigid PCBs and can be designed to accept virtually any necessary connectors. This makes flexible circuit boards ideal for many defense, medical, and aerospace technologies, like cryogenics, infrared imaging, and the construction of satellites, which often must withstand temperatures down to -150°F and up to 550°F.

Flex circuits can be printed single- or double-sided, multi-layer, or in combinations of rigid and flexible boards. All require unique processing in their fabrication. The choice for many designs includes thin, durable, material like Constantan in flexible PCBs. Constantan’s resistance remains stable across an extreme range of temperatures as well as in high pressure and other stressful situations. These qualities, plus its relatively low cost, have made Constantan foil a desirable conductive material for flex PCBs designed for hostile operating environments and rugged electronics.

In addition to solving the problem of thermal conductivity due to extreme external temperatures, Constantan in flexible PCBs can help maintain long-term reliability in situations when internal temperatures remain high. As electronics become faster and smaller, they require innovative designs and materials to deal with heat buildup. Along with the effective design of heat sinks and air flows, the use of Constantan as a conductor can lower thermal conductivity in flexible PCBs.

BGA-boards

The Benefits of Package-on-Package Assembly

Package-on-Package (PoP) is a type of IC packaging method that combines ball grid array (BGA) packages. In this method, two or more packages are vertically installed (i.e. stacked) with an interface that can direct signals between them.

Package-on-Package assemblyThere are two popular configurations for PoP assemblies:

  • Pure Memory Stacking: multiple memory packages are stacked on each other
  • Mixed Logic-Memory Stacking: a memory package is stacked on top of a CPU package

The packages are stacked on each other and attach to each other during reflow soldering.

There are several advantages PoP assembly has over tradition packaging methods:

  • Package-on-Package assembly more efficiently uses space, as packages are stacked vertically, increasing the effective space on the motherboard. The reduced space requirements for PCB assemblies caused by package-on-package assembly allowed smartphones and other compact electronic devices to achieve higher levels of performance without increasing in size.
  • Package-on-Package assembly also shortens the track length between components, causing better electrical performance as the shorter length will reduce noise and cross talk, and promote faster signal response.
  • Memory packages stacked in this fashion can be tested separately from the CPU package.
  • As long as the memory package fits on the CPU package, any memory package can be used, increasing flexibility in design.

Package-on-Package assembly is a delicate process and you should rely on an experienced and reliable PCB assembler such as IPC A-610 certified company like ACME PCB Assembly to build your products.
