Frequently Asked Questions

What is PCB assembly?

As mentioned before, PCB assembly means soldering electronic components on the printed circuit board. PCBs and components have their functions, but they can only work as fully functional products after soldering all of them together.

Do You offer quick-turn PCB assembly?

Definitely“Yes”. We strive to offer our customers quick turnaround PCBA service by all means so that your needs for quick turn PCBA will be satisfied.

Do you offer multi-layer PCB assembly services?

Of course, we can offer multi-layer PCBA services. We can offer any kind of PCB assembly service according to your expectation and requirements.

What is your standard turnaround for PCB assembly?

Standard turnaround time varies from the types and the quantity of the PCB assembly. The following are some examples.
1) Quick turn PCBA service takes 1-5 days.
2) It takes 1 week for only PCB assembly.
3) Two to four weeks are taken for turnkey PCB assembly or mass production.
4) Four to ten weeks are spent on Turnkey box build assembly.

What’s the PCB assembly cost?

The following is a brief overview of some of the factors that affect PCB assembly costs. 
1) Technology used: The assembly process may use either surface mount or through-hole technology. Sometimes, certain assemblies may require the use of both technologies, but this can add to the cost.
2) The number of layers of the board: The cost of a single-sided PCB assembly will usually be lower than the cost of a double-sided or multi-layer PCBA.
3) The size of the component: Typically, the use of smaller components and the fabrication of densely assembled boards will increase the cost.
4) The total number of components
5) Compliance: Multiple tests which are often performed to ensure assembly compliance also add to the cost.
6) Processes required: Some PCB assemblies may require a series of processes, such as wave soldering, X-ray inspection, automated optical inspection, manual soldering, and other processes. These may significantly increase the cost.
7) Flexible or rigid PCB assembly: Usually, the cost of flexible PCB assembly is higher than the cost of rigid PCB assembly.
8) Conformal coating: Costs are also affected by conformal coating requirements. The number of layers of the conformal coating can affect the cost.
9) Testing: From thermal cycling to circuit testing, many tests are required before shipping the products.
10) Packaging requirements: Special packaging requirements may result in increased costs.
Delivery: Costs may increase if expedited delivery times are required.

Anyhow, you just simply send an email to our sales team, we will quote you the price in 24 hours.

What is the difference between PCB and PWB?

PCB and PWB refer to the same item which is called differently. PCB is short for printed circuit board while PWB is an abbreviation for printed wiring board. So they are the same without a difference.

How is a PCB assembled?

There are many steps involved in the PCBA manufacturing process. In brief, the main steps are as follows.
Step 1: Adding solder paste: This is the initial stage of the assembly process. In this stage, the solder paste is added to the component pads in all the places where soldering is required. The solder paste is placed on the pads and pasted in the correct position with the help of a solder screen.
Step 2: Placing components: After adding the solder paste to the component pads, it is time to place the components. The PCB passes through a machine that places these components precisely on the pads. The tension provided by the solder paste holds the components in place.
Step 3: Reflow soldering: This step is aimed at permanently fixing the components on the board. After placing the components on the board, the PCB passes through the reflow oven conveyor. The controlled heat of the oven melts the solder added in the first step, thus permanently attaching the components to the boards.
Step 4: Wave Soldering: In this step, the PCB is made to pass through waves of melted solder. This creates an electrical connection between the solder, PCB pads, and component leads.
Step 5: Cleaning: By this step, all soldering processes are complete. During the soldering process, a large amount of flux residue is formed around the solder joint. As the name implies, this step involves cleaning the flux residue. Flux residue is cleaned with deionized water and solvent. With this step, the PCB assembly is completed. Subsequent steps will ensure that the assembly is completed correctly.
Step 6: Test: In this stage, the PCB assembly is completed and inspection begins to test the position of the components. This can be performed in two ways.
1) Manual: This check is usually performed for smaller components. The number of smaller components does not exceed one hundred.
2) Automatic: This check is performed to check for bad connectors, incorrect components, misplaced components, etc.

What is the minimum order quantity for PCB assembly?

There is no minimum order quantity for PCB assembly in Viasion. By the way, Viasion focuses on low-volume to medium volume PCBA service.
