How to Choosing a Printed Circuit Board Assembly Supplier

Tips of Choosing a Printed Circuit Board Assembly Supplier

A good printed circuit board assembly supplier can help you stay ahead of the competition. Not only will a reputable company be able to provide you with quality PCB assemblies, but they can also alert you to procurement issues or manufacturing issues and provide you with a range of helpful services, including engineering support. In this article, we’ll outline a few things you should keep in mind when choosing a PCB assembly supplier.

Printed Circuit Board Assembly Supplier 1 (20)


When selecting a Printed Circuit Board Assembly Supplier supplier, look for a supplier with extensive experience and the ability to meet your design specifications. Wholepcb, for example, offers turnkey custom printed circuit board assembly services. The company uses both manual and automated techniques to place PCB components. They are also capable of meeting the most demanding design requirements, including those of industries like Aerospace and Defense, LED lighting, and non-commodity consumer electronics.


Depending on the type of circuit board that you need, you can choose between FR-4 and FR-6. Both of these materials are flame retardant, which means they will not ignite. In addition, they are mechanically stronger, and will absorb less moisture. Which material you choose will depend on how your board will be used and how much you’re willing to pay. However, some time you may need other special material. You should check whether the Printed Circuit Board Assembly Supplier are able to supply or not.

Test abilities

After a supplier receives your purchase order, he or she must create an acceptance test procedure. This procedure must include equipment, test sequences, and criteria for accepting or rejecting products. The supplier must also submit documentation detailing the testing method and its outcomes, which must be included on the test data sheet. It must also include a serial/lot number, product name, and revision letter, along with a signature of a representative of the supplier.facilities
The next step in the PCBA process is to place the parts. Then, the board is placed onto pick-and-place SMD assembly machines. The efficient and precision assembling abilities depend on the supplier’s facilities advance or not. wholepcb, for example, has nine of these machines that can place approximately 20,000 parts per hour. After the boards are assembled, they are processed through a solder reflow machine, which fuses the solder paste into a permanent joint. This step is crucial for quality control.

Copper thickness manufacturing abilities

PCBs can vary in thickness, which is specified as the weight of copper per square foot. It is much easier to measure this in ounces per square foot, which is 1.344 mils or 34 micrometers. Heavy copper is a layer that exceeds three ounces per square foot, or 4.2 mils, and is used for high-current and heat-dissipating applications. Its thickness will depend on the electrical components used on the board. Different supplier may be able to manufacturing different copper thickness PCB. You should check whether the supplier can make the copper thickness you need.

Printed Circuit Boards Design Fabrication and Assembly

Printed circuit boards design fabrication and assembly is crucial for the production of electronic devices, such as mobile phones and computers. While this process was once a highly manual task, computers now perform the majority of the work. Machines are more accurate and speedy than humans. Humans can work fast, but they can also become fatigued after a few hours. A machine can work nonstop without getting tired. Here are some tips for designing and fabricating PCBs.

The design process of a PCB begins with the creation of a photomask on a clear sheet of mylar, typically two or four times its true size. The components were then arranged on the mylar sheet with their pin pads connected with traces. To improve the efficiency of the layout, common component footprints were pre-printed on mylar sheets. The photomask was then photolithographically reproduced onto blank copper-clad boards. In the process of fabricating PCBs, certain parameters must be kept in mind, such as the enclosure, heat sinks, and placement of components.

The thickness of a PCB’s copper layer is specified by its weight per square foot. This is more accurate, as one ounce of copper per square foot is equal to 34 micrometers, or 1.344 mils. A heavy copper layer is one that exceeds 3 ounces of copper per square foot. This is often used when the components are high-current devices that require a large amount of copper.

A PCB is a complex electronic device assembly that consists of conductive and insulating layers. The layers are laminated together to create a strong mechanical and electrical connection between components. The layout of a printed circuit board is designed to align with the structure of the bare circuit board and the manufacturing process. The printed circuit board is a complex piece of work, and a skilled team of engineers and designers can make yours the next time.

Printed circuit boards design fabrication and assembly is an intricate process that relies on precise data. When done correctly, it can ensure a high-quality device. It should not be rushed, and it should be designed and created according to a detailed blueprint. The process of printed circuit board fabrication begins with the design, based on the specifications provided by the client. The design phase of the PCB process consists of a detailed schematic, determining the desired function and use conditions. Printed circuit boards can be one, two, or even more layers.

The printed circuit board design process begins with the concept of the product. After capturing the schematic, the printed circuit board design lays out the physical circuitry on the board. The fabrication process is complete when components are soldered on the boards and the PCB is fully functional. Finally, the board undergoes assembly testing, verification, and testing, which demonstrates the final functionality of the device. These stages are vital to a successful project.
