Why You Need Custom Printed Circuit Boards

May 26, 2023 (updated July 10, 2023) | By Momentum | 0 Comments

Printed circuit boards (PCBs) are extremely versatile components with applications spanning consumer and industrial electronics, from a basic TV remote control to complex weapon systems for military and defense. They’re lightweight with an adaptable, compact design that allows them to be compatible with circuitry of varying configurations and complexities.

Customizing printed circuit board assemblies (PCBAs), and working with a trusted supplier, only enhances the benefits of standard boards and better tailors them to your applications. Read on to explore the components of a PCB and the benefits of custom circuit boards.

Custom Printed Circuit Boards: Components

A PCBA is comprised of various electrical components that enable essential functions and performance in its finished device. Each component serves a specific purpose, and the assembly will stop working if even a single component within it fails. The following parts are particularly important to PCBA functionality:

Resistors. Among the most important parts of PCBAs, resistors send electric current that generates a voltage and can then dissipate electric power in the form of heat. Color coding displays an assembly’s resistance value, and resistors are available in multiple material options.
Capacitors. After resistors, capacitors are the second most prevalent PCBA component. Within the PCB, they hold an electrical charge, letting it go when another area within the circuit requires more power. They typically achieve this by utilizing two layers of conductive material and a separating layer of insulation to collect opposing charges.
Inductors. When current passes through them, inductors store energy as a magnetic field. These components perform similarly to capacitors, and they can block interference and related signals originating from another device.
Transistors. Transistors act as amplifiers, managing electronic signals on the PCB. There are various types, but the most popular is the three-pin bipolar transistor, consisting of a base, emitter, and collector.
Transformers. By raising or lowering voltage, transformers typically pass electrical energy between circuits.
Diodes. As components within a circuit, diodes permit the flow of electrical current in a single direction but restrict it in the other to prevent damage to a component or the PCB. Light-emitting diodes (LEDs) in particular are a popular variety as they give off light.
Sensors. Sensors detect environmental changes, producing a corresponding electrical signal to communicate the specific change to another part of the PCB. Essentially, sensors serve as transducers, taking physical changes in air quality, sound, or light motion and translating them into electrical energy.

Custom Printed Circuit Board Assembly Benefits

Custom assembly benefits device and equipment manufacturers as well as their customers with optimized, cost-efficient PCBs and full design flexibility.

Technical Advantages

Custom PCBA design gives the manufacturer complete control over the component and circuit locations on the board down to a fraction of an inch. Improved control over component location helps manufacturers avoid the parasitic properties of the circuitry. By mounting components on the board’s surface, they can reduce the potential for parasitic inductance that’s inherent to through-hole component alternatives.

Custom PCBA design delivers:

Higher-quality assemblies with repeatable accuracy
Improved assembly organization
Reduced assembly size and condensed circuitry to save space
Ease of maintenance and service for OEMs
Reduced installation, service, and replacement labor
Reduced costs due to decreased labor expenditures and improved precision from automated production
LED light integration for fast diagnostics and functionality verification
Legends printed directly on the board to make decals unnecessary

Fewer Labor Costs

Labor expenditures rather than materials are the leading contributor to the overall cost of production. Designing a custom PCBA can reduce these costs considerably in the long run by lessening the need for modifications and re-work. Once the initial PCBA prototype is finished and they’ve verified its performance, manufacturers can use the approved design schematics to replicate the PCBA.

Flexibility

Custom PCBA designs offer manufacturers the freedom to select the ideal size, shape, and power for their application. They can also make a range of modifications or fixes throughout the design and assembly processes.

How To…Operate a Selective Soldering Machine

May 17, 2023 (updated July 10, 2023) | By Momentum | 0 Comments

What are Selective Soldering Machines?

A selective soldering machine is a specialized machine that applies molten solder to specific points on a circuit board. In the manufacturing of electronic devices, they connect components and ensure a strong, reliable electrical connection.

The Components

The machine typically consists of several key components, including a solder pot, a preheat station, a nozzle, and a control system.

Solder Pot

The solder pot holds the molten solder and heats up to the appropriate temperature for the specific type of solder.

Preheat Station

The preheat station heats the circuit board before the application of the solder. This component helps to prevent thermal shock and ensures a strong, reliable solder joint.

Nozzle

The nozzle dispenses the molten solder onto the circuit board. The commands of a computer program tell the nozzle how to function. This process allows for a high degree of accuracy and control.

Control System

The control system is the center for human interaction with the machine. This is the component that allows an operator to maintain surveillance and control.

Operating Process

To operate a selective soldering machine, the operator first loads the circuit board onto the machine’s conveyor system. The circuit board moves through the preheat station to heat it to the appropriate temperature. The operator then uses the machine’s control system to program the machine to apply the solder to the specific points on the circuit board where the component connections need to take place.

Once the machine is programmed, the operator starts the process and the machine applies the molten solder to the specified points on the circuit board. The operator then inspects the circuit board to ensure that the solder’s application is correct and that there are no defects. If there are any defects, the operator can adjust the machine’s settings and re-run the process to correct the issue.

It’s important to note that for selective soldering, a good setup and maintenance of the machine are crucial for the quality of the solder joints. This includes regular cleaning of the nozzle, regular calibration of the machine, and ensuring the correct temperature of the solder pot.

In summary, selective soldering machines are specialized machines that are used to apply molten solder to specific points on a Printed Circuit Board Assembly (PCBA). A computer program controls the machine, and they require an operator to load the circuit board, program the machine, and inspect the circuit board for defects. With proper setup, maintenance and operation, selective soldering machines can produce high-quality, reliable electronic devices.

Selective Soldering Process

May 8, 2023 (updated July 10, 2023) | By Momentum | 0 Comments

The Selective Soldering Process

Selective soldering is a key step in the electronics manufacturing process that requires specialized equipment, skilled operators, and careful control of the soldering process. As a leading electronics manufacturing service provider, PGF Technology Group has extensive experience in selective soldering and a commitment to quality, reliability, and efficiency in every aspect of our operations.

Why Use Selective Soldering?

Selective soldering joins components to the printed circuit board (PCB), creating a finished assembly. The process is “selective” because it involves the application of soldering only to specific areas of the PCB, rather than to all connections. This is important because not all components can withstand the high temperatures for reflow soldering. Reflow soldering is the standard process in the manufacturing of most electronic assemblies. Selective soldering allows us to protect delicate components and ensure that they are secure to the PCB, while also providing a reliable and consistent connection.

What are the steps of the Selective Soldering Process?

The selective soldering process typically begins with the application of flux to the pads and leads of the components. The flux helps to prepare the surface for soldering and to promote good wetting of the solder to the pads. Next, the machine places the components on the PCB, and the selective soldering equipment applies the solder. The equipment uses a combination of heat and pressure to melt the solder and join the components to the PCB. The machine carefully controls the temperature and duration of the soldering process to ensure consistent results. The operator monitors the soldering process to ensure that each joint is soldered to the correct specifications. Here is the step-by-step explanation:

1. Preparation:

Before the selective soldering process can begin, the machine and operator prepare the PCB by applying solder paste to the appropriate areas of the board. Prep work includes a stencil or a screen printing process.

2. Component placement:

Once the solder paste has been applied, the surface-mounted components are placed on the PCB using pick-and-place machines or other automated equipment. The components are typically held in place by a temporary adhesive or vacuum.

3. Flux application:

The machine applies flux to the areas of the PCB where it will apply the solder. Flux is a chemical that helps the solder flow and adheres to the PCB and component leads.

4. Preheating:

The machine preheats the PCB to activate the flux and remove any moisture from the PCB and components. The preheating temperature is typically between 120-150°C.

5. Selective soldering:

The selective soldering machine applies molten solder to the areas of the PCB that require soldering. The machine uses a solder nozzle to apply the solder in a precise and controlled manner.

6. Cooling:

After the soldering is complete, the machine cools the PCB to solidify the solder and ensure a strong bond between the components and the PCB.

7. Cleaning:

The machine then cleans the PCB to remove any excess flux or residue from the soldering process. This cleaning uses solvents, ultrasonic cleaning, or other methods.

8. Inspection:

Finally, the machine inspects the PCB to ensure that all components are secure and that there are no defects in the soldering process. This may involve visual inspection, automated optical inspection (AOI), or other testing methods.
