  1. Why Is It Important to Be on the Edge of Technology?

    Leave a Comment


    You are searching for a manufacturer on the edge of technology to partner with for your new PCB assembly project. 

    Company A and B both offer low volume, high mix capability for PCB assemblies. Company A has the most effective technology to perform highly replicable automated processes alongside manual assembly. At the same time, Company B relies on mainly manual labor and has not replaced its machinery in 10 years. Both assembly methods can be effective, but one shortens the timeline and increases product accuracy. 

    Which company do you choose? 


    What Does “Edge of Technology” Mean?

    The phrase “Edge of Technology” refers to a company constantly remaining ahead of the curve in the latest machinery and equipment. Specifically, this phrase has a connotation that includes a look into the future. In essence, I mean that the word “edge” alludes to something about to move forward; it predicts movement that propels and builds kinetic energy. To clarify, an edge represents the end of a corner and the beginning of another, forcing a step onward. 

    As can be seen in manufacturing, staying informed about upcoming trends and techniques allows a company to predict its next moves in new machine purchase, installation, and usage


    Why is it Important to Be Constantly Innovating?

    Ultimately, the push to constantly innovate is about staying one step ahead of the customer and competition. In terms of a partnership, both sides must match up to expectations. For example, if a customer requires the newest model of a specific machine that you do not have, then they will find a different partner.

    Electronic Manufacturing Suppliers (EMS) must think about a customer’s future projects. To be a proper solutions provider, you have to answer the question before it’s asked. This practice begins with prediction, preparation, and execution. In this case, a manufacturer must reflect on:

    For which industries do I want to do assembly?

    Specific industries may have certain technologies that manufacturers must use to complete a project. This distinction is especially true in advanced Medical Devices and the highly inventive EV Power Industry.

    Where are these industries headed?

    Any manufacturing company must remain privy to the advances driving ambitious projects. From trade shows to industry updates, companies have to envision the next direction for their current and potential customers. 

    What machinery do the potential projects require?

    In order to prepare for the future, companies must have close relationships with their customers to learn about the needed machinery. Collaborations between growing businesses allow for a wide range of innovation with an emphasis on state-of-the-art equipment.

    At this point, for PCB Assembly, Cable Harness Assembly, and Wire Processing, PGF utilizes advanced operational technology

    With an array of Schleuniger machines for crimping, stripping, and terminating, wires can be processed and sorted quickly with a team of skilled workers operating the machine and perfecting the project. 

    On the other (electronic) side, Selective Soldering machines, Solder Paste Inspection (SPI), and Surface-Mount Technology (SMT) lines place components accurately on their respective PCBs and use reflow soldering to keep them in place. Our team utilizes a Fuji Line and MyData Line to assemble various volumes of PCBAs. 

    An X-Ray machine, In-Circuit Testing devices, and Automated Optical Inspection (API) machines allow close quality inspection. These machines act as second eyes to check PCBA performance.

    With many additional automated and hand equipment, we raise the bar to move forward continuously.

  2. Parts of a Printed Circuit Board Assembly

    The “A” in PCBA

    Printed Circuit Board Assemblies (PCBAs) are electronic assemblies responsible for connecting the electrical components of a system or device. Their applications range from everyday staples such as smartphones to complex custom box build assemblies. The difference between a PCB and PCBA is the A – Assembly of components to the board. Thinking about a PCB layer as a floor, the PCBA represents the completed building – all stairways and connections built to create a fully functioning operation.


    What Are the Components of a PCBA?

    PCBAs are flat, thin substrates covered in conductive metal and circuit components. Copper lines, called traces, allow electricity to flow into different board components. In turn, the solder mask insulates the copper traces from other metal parts that might accidentally touch them. Some traces remain exposed so manufacturers can solder components to them.

    The following is a closer look at a few of these PCBA components:


    ResistorsResistors regulate the electric current passing through them and indicate their resistance level through color-coding. Resistors are essential because they can guard fragile components against voltage spikes within the circuit. Additionally, if an element needs a lower voltage than the rest of the circuit, a resistor can drop the voltage to the required level.


    TransistorsTransistors are semiconductor devices that can control or amplify currents. Small currents applied to one of the transistor’s three terminals control these functions.


    CapacitorsCapacitors can store electricity and release it when a different component in the circuit needs more power. If there is any fluctuation in the circuit’s exact voltage, capacitors can store excess charge and release it as required.


    InductorsInductors store energy in the form of a magnetic field. Since they have power separate from the circuit’s current, they provide current to the circuit even when the switch is off.


    TransformersTransformers transfer current from one circuit to another using wire coils. Running electricity through the wire coils from one circuit produces a magnetic field that reaches the other circuit’s wire coils. The magnetic field creates a current in the new circuit’s wire coils. We can control the amount of current generated by changing the number of turns of the coils in each circuit.


    DiodesDiodes / LEDs are elements that only transmit current in one direction and block current in the other direction. In most cases, diodes usually have coloring to note the end that allows flow and the one that does not. They protect fragile electronic components from receiving current from the wrong direction. LEDs, or light-emitting diodes, are a particular type of diode that emits light.


    SensorsSensors can detect a change in the environment around the board and translate that into electrical charge. For example, a light sensor can see when it’s getting dark and send current to another element in the circuit, like an LED.


    SwitchesSwitches can only be open or closed. If the switch is open, then it allows the current to flow. The switch blocks the current from flowing through the circuit if it is off. This component enables more control of the operator.


    How Do Manufacturers Attach Components to a Circuit Board?

    At present, Electronic Manufacturing Service (EMS) Providers can attach these components to a printed circuit board through various forms of manual and automated assembly. Even more, two of the most popular are surface mounting and through-hole mounting.


    • Surface-mount technology (SMT) is the master of all domains in PCB technology. In detail, it refrains from using drilled holes to attach PCBA components; all components are placed directly onto the circuit board. Assembling circuit boards using SMT automation is the simplest and cheapest method, and it allows full utilization of both sides of the PCB.


    • Thru-hole mounting is the old reliable mainstay for secure builds. Pre-drilled holes connect components to the board. Since they are soldered in place, the components can withstand more stress. These boards cost more to manufacture and are more difficult to modify than surface-mounted PCBAs, so this method is better suited for mounting connectors and large components that need extra attention. In large part, this assembly method is behind the times, remaining useful for unique builds.
