Q: Printed Circuit Board Assembly: Parts on Both Sides?

Image
A: Components can be placed on both sides of a printed circuit board assembly. This is a “double-sided” or “two-layer” PCB design. It allows for more compact layouts and better utilization of space. However, it requires careful consideration of component placement, routing, and   soldering processes   to ensure proper functionality and   manufacturability . Placing components on both sides of a PCB can help optimize space and layout, allowing for more complex circuit designs. However, designing and manufacturing double-sided PCBs can be more challenging than  single-sided  ones, as it requires careful planning of component placement, signal routing, and ensuring proper clearance and alignment between components on both sides. Double-sided PCBs can have  vias  (electrical connections between the top and bottom layers) that allow signals to pass between the layers. Vias can be through-hole (going entirely through the board) or surface-mount (connecting t...

Wiring Harness or Cable Assembly: Which is it?

Image
Do you know the difference between a wiring harness and a cable assembly in the electronic manufacturing industry? The terminologies are often interchanged, but the two are significantly different. Consider this answer ( ANZER ) to help facilitate your comprehension when sourcing fabricated interconnect products. Wiring Harness: A wire is usually made of a conductive metal like copper. It can be an individual or group of metal strands covered by an exterior sheath. This covering substance is typically made from rubber, thermoplastic, or a vinyl compound. The wire only has a heat-shrunk covering or jacket around the conductive strands. Several of these individual covered wires bond with tie wraps or similar banding material to make up a wiring harness. Wire harnesses can be advantageous since they are smaller, lighter, and typically less costly than cable assemblies. However, these are inadequate replacements for cable assemblies regarding protection against environmental ...

What is Aerospace Customer Quality Service?

Image
An example best explains the answer ( ANZER ) to this question since we had the pleasure of hosting one of our aerospace customers this past week. We have been producing several modules for them for many years, which include installing tiny gauge wires called flying leads. Their senior quality management shared the challenges of interconnecting those wires to their base system despite doing so for years. During their visit, our quality manager reviewed how the wires were installed on the module via hand soldering by one of our expert technicians. Ensuring the height of the exposed portion of the wire lead above the printed circuit board (PCB) was strictly within IPC guidelines . This is done to ensure the reliability and integrity of the solder connection. We should also mention that the same technician has hand-soldered these same modules for over 20 years! Once these modules are conformally coated, a wire stiffening material is applied to help support the fine gauge wires. Then they...

Through-Hole Versus Surface Mounting

Image
In recent years, semiconductor packaging has advanced with an expanded demand for more extensive functionality, smaller size, and added value. A modern PCB assembly design has two central methods for mounting components onto a printed circuit board: Through-Hole versus Surface Mounting. Through-hole components are mounted on a printed circuit board (PCB) by inserting their leads or terminals through holes in the board and then  soldering  them onto the opposite side. Surface mount components, on the other hand, are mounted directly onto the  surface of the PCB  without the need for through holes. They are soldered onto pads on the surface of the printed circuit board. The main difference between  through-hole  and surface-mount components is how they are mounted and soldered onto the PCB. Through-hole components are usually much larger and have wire leads or terminals inserted through holes in the PCB. To ensure stability, they often require additional mech...

PCB Lines and Traces: Why Size Matters

Image
The sizes of PCB (Printed Circuit Board) lines and traces can vary widely depending on the specific design requirements, the   technology used in manufacturing , and the application of the PCB. Here are some typical sizes for different types of PCB traces: Minimum Trace Width and Spacing : The minimum trace width and spacing are determined by the capabilities of the PCB fabrication process. Standard minimum values for a typical  2-layer PCB  might be around six mils (0.006 inches) for trace width and spacing. However, advanced processes can achieve much finer widths and spacings. High-Speed Traces : For high-speed signals, like those used in  high-frequency applications  or digital signals with fast edges, trace widths need to be wider to maintain signal integrity and prevent impedance mismatches. These traces could range from 10 mils to 20 mils or even more expansive, depending on the specific requirements of the design. Power Traces : Traces that carry higher ...
