1, What Is A Turnkey PCB Assembly Order?

Turnkey is a term for the service where you have to provide us documentation or files, and we will build the PCB from scratch by selecting the board-level components, materials, and the SMT stencil. We will return the assembled PCBs to you.

2, What Documentation Or Files Are Required For A Turnkey Assembly?

  • Your Gerber files including top and bottom silkscreen, solder paste layers, and copper layers
  • The Centroid data file featuring rotations, component locations, and reference designators
  • BOM (.xls) with vendor’s names, quantity, reference designators, part and package descriptions, and quantity
  • Types of components including SMT, thru-hole, fine pitch, BGA, and more
  • Any additional instructions and requirements

3, What Is The Lead Time For A Turnkey PCB Assembly Order?

Assembly lead times quoted to the client exclude the procurement lead time. The lead times for the turnkey order entirely depend on the time required to source the part. The assembly begins only after all the components are available in the inventory.

4, What Happens To The Leftover Or Unused Components On Turnkey Orders?

The components that have limited uses are returned to the customer along with assembled circuit boards. However, other components are retained in our inventory.

5, What Are Turnkey Projects Typically?

Turnkey (or turn-key) project is a term typically used with reference to construction projects for which the developer undertakes the whole responsibility from design to completion so that the building is available to the buyer in a ready-to-use condition.

6, What Is PCB Assembly Process?

A PCB with components mounted on is called an assembled PCB and the manufacturing process is called PCB assembly or PCBA for short. The copper lines on bare board, called traces, electrically link connectors and components to each other.

7, What Is The Minimum Order Requirement For Turnkey PCB Assemblies?

There are no minimum order requirements. However, we always inform our clients that larger orders will help them save more money. If you discuss your requirements and budget with our experts, we can help you find the right solution according to your needs.

Turnkey PCB Assembly: The Ultimate FAQ Guide

The most obvious benefit of turnkey PCB assembly is that businesses don’t have to take their focus off critical processes like continual innovation to spend time figuring out the assembly side.

There’s no need to expend time and energy finding the best component costs, going through a frustrating process of procurement, and then needing an in-house team to assemble them skillfully.

With a turnkey contract, there is no extra cost to deliver freight to an assembly workshop, meaning you save a significant amount of money.

Turnkey services also have good working relationships with component manufacturers and can almost always get a better price for parts than small or medium businesses.

Most entrepreneurs and manufacturers find the old method of manufacturing electronic products and printed circuit board components very intimidating.

Because it is slow, error-prone, and expensive. It is not designed for small batch runs and prototypes, but to support a large number of orders and requires a long preparation time.

Fortunately, Turnkey PCB Assembly services are now meeting the needs of hardware designers.

As one of the high quality-focused PCB manufacturers that include electronic assembly services, PCBMay has more than 10 years of experience in providing fast, reliable turnkey PCB assembly services for more than 8,000 companies from over 60 countries around the world.

Our single-source approach saves you time and money, while also ensuring more reliable, consistent results than when dealing with several suppliers.

What is Turnkey PCB Assembly

Turnkey PCB Assembly is a new method for electronic assembly influencing onshore PCB manufacturing and cloud-based software to generate stress-free and fast emerging printed circuit boards for:

  • Entrepreneurs
  • Manufacturers
  • Engineers
  • Small businesses.

With this, you just have to upload the design of your files and immediately receive a quote and the rest will be under the care of the manufacturer.

When the most innovative small businesses and startups need to make use of printed circuit boards (PCBs), they often find that, when it comes to assembling those PCBs, they face certain challenges, like the need to carry a large inventory and have an in-house team to create it.

Turnkey PCB assembly is an electronic assembly solution offering efficient and cost-effective means of building and testing circuit boards for new products, with the shortest lead times possible.

In this guide, we’ll discuss the meaning of turnkey solutions for PCB assembly and the benefits associated with it.

Turnkey PCB assembly is taken beyond the boards by providing a quick and comprehensive solution.

The Meaning of “Turnkey” in PCB Assembly

The meaning of “turnkey” projects is any product or service that comes ready for the buyer to operate. In terms of PCB assembly, turnkey PCB assembly is a service where all aspects of the PCB project are handled by your supplier on your behalf.

The supplier procures parts and components and assembles the PCB.

Turnkey PCB assembly typically uses cloud-based software and powerful machinery to put together circuit boards more efficiently and at a greater volume than small and medium businesses can handle on their own.

Benefits of Turnkey PCB Assembly

Hardware designers are delighted with the new opportunities offered by turnkey PCB assembly.

Some of these outstanding opportunities include:

Producing your first prototype is usually a very slow and expensive process.

With this, tasks like out-of-stock components, slow delivery times, and keeping up with many sellers around the world become tedious.

With Trunkey’s PCB assembly, prototyping is now possible more efficiently and effectively.

It has never been easy to iterate your product and get to market quickly and cheaply.

As a general rule of thumb, the following are the most important factors when looking for a PCB Turnkey Service

1 Quality of Boards

One of the most important factors to consider is always quality; every individual or company would certainly always want the highest quality of boards going into their products.

Generally speaking, a high-quality board would have tight tolerances on crucial things.

These include trace width and spacing, the position and size of all drilled holes and vias along with an accurate trace copper thickness.

High-quality boards will also have a very accurate layer stack-up, which is especially useful when your design contains features like impedance-controlled traces.

2 Manufacturer’s Technological Capabilities

The other important factor when choosing a PCB turnkey service is always the fact that whether your board manufacturer can manufacture your design requirements.

Some composite boards may have multiple layers. Sometimes up to 24 Layers and above.

Other boards may be extremely small and have very thin traces and clearance constraints.

Not all manufacturers can handle such specifications. Even a high current board that requires a high copper thickness would need to be sent out to a Turnkey PCB Assembly service that can make your board with higher than standard copper thicknesses.

 3 Cost

Cost is always a governing factor; The value of the PCB sometimes is a significant contributor to the value of your finished product.

To make sure your product has a sufficient profit margin, a customer must choose a PCB turnkey service that offers reasonable pricing options and yet delivers excellent quality for the price.

4 Customizability Options 

Most Turnkey PCB Assembly companies will offer a variety of customizability options.

These can be features like the choice of solder mask color. Whether you need to pre-test the board and more unique features, such as adding serialization, filling Vias, etc.

It is essential to choose a manufacturer that can match your customizability needs.

Some services might offer many more options compared to others.

A simple example here can be the choice of solder mask color, while one manufacturer may only provide two colors, others may offer more than 4-5.

Other than just manufacturing PCBs, a full Turnkey PCB Assembly service will also offer the service of PCB assembly.

PCB assembly would mean getting all components in your design soldered onto the PCB.

It is a precious service, especially if your boards have a lot of small surface mount components, and the board needs to be mass-produced in high numbers.

The assembly is usually done using high-end pick and place machines and reflow ovens which a small company may not be able to afford or have the expertise to use, hence it makes a lot of sense to get PCBs assembled by a turnkey PCB assembly service.
