Introduction to PCB Assembly
What is a PCB Assembly (PCBA)?
In simple terms, Printed Circuit Board Assembly) is a board presented after the entire parts and components get soldered and rightfully installed.
A PCBA is the combination of the PCB plus components plus electronic accessories.
The PCB board uses conductive tracks and copper features to structurally support and electronically connect the various components to insulative substrates.
When other components, such as capacitors, resistors, integrated circuits (ICs), transformers, etc., depending on the intended use, are mounted on the PCBs, the resulting board is a Printed Circuit Board.
The Assembly board is presented after the parts and components are soldered and rightfully installed.
Why outsource PCBA?
In the past, it was a common practice for companies to fabricate and assemble their PCBs in-house.
This approach is very costly because it requires investment in real estate, machinery, facility development, and staffing.
As a result, only companies with substantial investment capital could establish equipment manufacturing companies.
Today, with several small—to medium-sized Original Equipment Manufacturers (OEMs), fabricating and assembling PCBs in-house is impracticable.
Therefore, the assembly of PCBs can be outsourced to companies that provide PCB Assembly services.
Because they specialize in assembly services, a PCB’s Bill of Materials (BOM) is fitted onto a board because they specialize in assembly services.
PCB assembly companies can produce high-quality PCBs with a low-cost budget and fast turnaround time.
Furthermore, they usually have highly sophisticated facilities that allow them to produce even the most complex PCBs.
However, it’s not just about outsourcing your Bill of Materials (BOM) for a PCB to be fitted onto a board.
PCB assembly is about outsourcing it to the right company.
The right assembly company best suits your quality and delivery time requirements at the lowest cost.
The PCB Assembly Process
Before you even consider getting an SMT.
This will make it easy for a pick-and-place machine to place the components on the PCB (PCB assembly company). You must understand what it entails.
As we’ve defined before, PCB Rapid Prototyping. 3D PCB Printing makes the PCB and does the Printed Circuit Board Assembly (PCBA), which adds components to the PCB board.
There are two main processes for performing SMT). This will make it easy for a pick-and-place machine to pick and place the components on the PCB easily.
Surface-mount Technology
It is the most prevalent assembly method used in several electronic gadgets. In this method, components are directly mounted on the board’s surface.
This method can create very compact PCBs. Specifically, a PCB assembly made with the through-hole method can be made with surface-mount technology with just 10 percent of the board weight and 30 percent of the board size.
This higher connection density allows for quicker and cheaper board production.
Through-hole Manufacturing
It is a more ancient method of SMT. This method involves drilling holes in the circuit board, making it easy for a pick-and-place machine to place the components on the PCB (PCB assembly).
After that, the components or units are fixed in the holes by padding their sides using soldered leads. Because of the stronger bond between the components and the board, PCBs manufactured with this method are usually more durable.
However, this approach is more expensive and time-consuming.
Through-hole manufacturing remains the best option for executing their PCB assembly for transformers and connectors destined to undergo high mechanical, electrical, or environmental stress.
If the equipment you are trying to build fits the description above, through-hole manufacturing is the best bet.
If not, using the surface mount technology may be preferable. Sometimes, both methods are combined for PCB assembly, depending on the project’s requirements.
Factors to Consider when Selecting PCB Assembly Services
The success of your project depends on having the right SMT. This will make it easy for a pick-and-place machine to place the components on the PCB (PCB assembly service).
However, selecting the right one from the numerous SMTs will make it easy for a pick-and-place machine to place the components on the PCB (PCB assembly services can be daunting).
The following factors are a well-proven guide that will ensure that you partner with the right PCB assembly company that will allow you to accomplish your goal.
Alignment of Timelines
To minimize expenses and maximize profits, it is essential that all phases of production, including the assembly, follow the timeline, as delays would lead to an unnecessary cost burden.
Therefore, you want a PCB assembly service that can work within your time frame.
For example, if a company is slow at responding to your queries or you need to request information multiple times before getting feedback, it is a good indication that they might be a drag later on.
To small-sized OEMs, such delays can have a devastating impact on your business.
Therefore, ensure you do your homework effectively to ensure the company’s operation timeline works correctly.
Location
Many buyers also consider location and distance, as they affect transportation costs. However, many Chinese manufacturers, such as WellPCB, offer online calculations to get shipping costs and total prices quickly.
Sometimes, for different countries, there are different discounts for shipping by DHL, so even if you feel that the distance is very far, the shipping price is not necessarily expensive.
Experience
Working with experienced PCB assembly companies similar to your project is best. Some critical questions to be answered regarding experiences include the following: What assembly technology do they specialize in—surface mount, through-hole, or both?
What batch size do they use? What kind of gadgets do they assemble, and what are their usual components? What industry do they specialize in?
Your goal is to find a PCB assembly service that perfectly aligns with your job requirements. Part of gathering information about their experience is also finding out how long they’ve been in business.
By partnering with companies that have been in business for a long time, you can guarantee that the people who work on your project have the expertise you need to create the best products for you.
