Prototype PCB Assembly Services from PCBasic

The journey to manufacturing the correct electronic equipment begins with ordering a prototype PCB assembly. Imagine, after mass production of an electronic circuit board, you realize you made a mistake in the design. And that would mean starting all over the process. Not to mention the financial loss.

You can avoid such costly mistakes by going for PCB prototype assembly services. It lets you scrutinize your circuit board design and subject it to several functional tests. After that, you can launch the mass production of the assembly board without any fear. 

The article takes you through the PCB assembly process, why it's necessary, and how to make an order for a PCB prototype assembly.

  

What is Prototype PCB Assembly?

A printed circuit board assembly has complete components on it. After making new PCB designs or after effecting some changes, you need to confirm that there are no errors. Therefore, that calls for ordering the manufacturing of a sample printed circuit board. 

A prototype PCB assembly is thus the testing assembly you order before beginning mass production of the board for commercial purposes.

It’s cheap and convenient to correct errors on a PCB prototype assembly. On the other hand, errors in a whole batch mean wasted time and money.

Benefits of Prototype PCB Assembly Services

Collaborating with a reliable company to handle your prototype PCB assembly services bestows you additional benefits:

Cutting Down on Timeline

The design teams test the individual components and the prototype. Whenever they unearth any mistakes, they fix them before reaching the consumer.

Also, presenting a sample before your potential customers is more convincing, which means less back-and-forth communication about the product.

Assistance From the Manufacturing Team

You also benefit from the assistance of the manufacturing team. For instance, our professionals can suggest ways of improving the design to maximize its performance. Also, our prototyping team can point out potential mistakes DRC or you hadn’t spotted before.

Reducing Costs

One of the outstanding benefits of PCB prototype assembly is cutting down on production expenses. By pointing out errors before going for full-scale production, you avoid paying double the amount for the production of the items.

Estimating the Quantity of Materials and Production Time

After running a successful prototype, you can approximate the demands of full-scale production. That is the projected timeline and range of materials it will take.

Verifying Concepts

A design theory may appear convincing on paper. However, prototyping is solid proof of the working of an idea to improve a product.

Our Prototype PCB Assembly Process

Design and Consultation

First, our team of professionals receives the Gerber design files and other vital instructions from the customer. After receiving the file, we don’t just begin the prototype PCB assembly straightaway.

Instead, we have a dedicated team that uses the advanced DFM tools to verify the functionality of the board. The board house checks on possible issues that might hinder the smooth functioning of the board.

 

When we notice any missing information or poor spacing of components, we consult with the customer to correct the anomaly in time. The purpose of the design and consultation stage is to identify and eliminate any potential problems that might bring about unnecessary expenses. 

Component Sourcing

PCBasic has been in operation for more than 10 years. Over the years, the company has waded out unreliable suppliers. 

On the contrary, we have forged strong ties with reliable manufacturers of top-quality SMT components. So, you can rest assured that we only use high-quality parts in the PCB prototype assembly services. 

Although we have reliable components suppliers, we aren’t taking any chances concerning the quality of materials and components. 

That’s why we have a strict, accurate, and automated incoming quality control inspection system. The automated IQC system verifies the following on the resistors, capacitors, inductors chips, and other components:

● Components quantity and model number to match the BOM list

● Broken pins, deformed or oxidized chips

● Taking random samples for testing to verify their functionality and accuracy

If the system detects any discrepancy or low-quality components, we discard and return the components.  

Assembly and Soldering

After verifying quantity, quality, and model number to meet our threshold, the process moves onto the assembly and soldering stage. In the preliminary stage, our PCV assembly team uses the Gerber data provided by the customer to manufacture the bare printed circuit board.

After that, the prototype PCB assembly and soldering involves the steps below：

Stencil Fabrication

Here, we tap on the laser cutting stencil technology. That's because it's pocket-friendly and gives efficient results. 

Incoming Inspection 

Before beginning the assembly, we have to inspect components to verify their quality and if they match the customer's specifications. 

Components Baking

After confirming the originality of the parts, they passed on to the baking. Components baking eliminates the bubbles and thus gives efficient results. The baking time varies from component to component. For example, LED requires 4 hours, and ICs about 12 to 24 hours. 

Solder Paste Printing

The success of this stage depends on using the right solder quality and making the perfect SMT stencil. Therefore, PCBasic uses the Alpha from Japan. Although it is slightly expensive, Alpha tin solder paste is efficient and gives superb results. 

Components Placement

Manual picking and placement of components can be slow and straining for the eyes after working for long hours. So, at PCBasic, we use the pick and place machine JUKI from Japan. The machine fits the prototype PCB assembly service because:

● Doesn’t suffer the pressure of work like manual pick and placement by hands

● Picks and places the exact components at a faster speed

Reflow Soldering

Before reflow soldering, the automatic optical inspection machine (AOI) confirms the correct placement of each component. It does that by comparing the Garber data versus the actual placement of parts. After the verification, the reflow soldering begins.

First, we set the correct reflow soldering temperature of 10 degrees. Such heat level is friendly to the components, easy to control, and thus gives optimum results. At the end of the process, the solder solidifies and the components adhere to their respective places. 

Post AOI

Once the solder solidifies, the prototype PCB assembly process proceeds to the post-AOI stage. The post-automatic optical inspection stage checks for poorly soldered joints and shots between points. 

Often mistakes arise if any movement occurs during the reflow process. Besides using the AOI machine, X-rays can also help check for faults.

The AOI machine has cameras at strategic angles to the board. By reflecting light on the board at high resolution, the machine reveals the nature of the solder joints, whether it’s poor or excellent.

Unlike annual inspection by hand, the automatic process is fast and fits large batch boards and even those with high-density components. If our team unearths any faults, they rectify them quickly. Next is cleaning of the board before proceeding to the through-hole PCB assembly.

Through-hole assembly

Some multi-layered boards call for incorporating through-hole components. The whole assembly may take unique soldering styles such as:

Hand Soldering

It’s a method where each person inserts a through-hole component into a particular area. That goes on until the last person fits the last component. As noted, the process is time-consuming and tiring. 

Wave Soldering 

After inserting all the through-hole parts, a wave of molten solder is passed over the bottom section of the board. When that happens, all the pins sticking out get soldered. The wave soldering technique isn’t ideal for double-sided boards as it can disengage all the previously soldered components. 

Testing and Quality Control

Before packaging and shipment of the product, it undergoes functional testing. That involves powering and feeding the prototype board with simulated signals. 

The experts then note the output characteristics. If it resonates with the predetermined range, the test is successful. Usually, clients spell out the kind of test to run on the PCBA and projected output.
