Time-to-market is connected directly to the turnaround time hence having a significance in the success of a company.

Inquiries should be made to find out if standard turn-around time for other PCBs is same as your project.

It is wise to also ask if project can be expedited and the procedure.

Partnerships with contract manufacturers should be based on open communication and trust.

A good relationship will avoid delays due to a good time-to-market efficiency therefore gaining the company a market advantage.

Acceptance Quality Level Or Yield Rate

Manufacturing a tangible PCB is insufficient if its quality is questionable.

It is therefore very crucial to question any potential contract manufacturer about their yield rates for PCBs and quality standards.

The AQL shows the largest number of faulty parts before rejecting a batch.

It also designates the minimum tolerable level of quality in a predetermined sample size.

Is Contract Manufacturing For PCB Cost Effective?

It is very cost effective compared to self-manufacturing.

Running and maintaining manufacturing facilities in-house is very costly in terms of operation costs especially for startups and small firms.

What Should You Focus On When Getting A Quote From A Contract Manufacturer Of PCBs?

To quickly and accurately acquire a quote from Contract Manufacture for your PCB, detailed focus should be put on the above areas;

Bill Of Materials

One of the things a contract manufacturer will ask for upon contact will be the Bill of Materials or BOM.

This is a detailed list that contains the raw materials to be used, the components involved and other vital information for the manufacturing of the PCB.

This assists in identifying a sanctioned list of Contract Manufacturers and a comparison done on the PCB materials and components.

It should be presented in a non-editable form to restrict unsanctioned changes.

PCB Testing

The contract manufacturer should avail a wide range of options for PCB testing.

The preferred testing procedure should be indicated to the contract manufacturer to be performed on the PCB assembly.

Other unique requirements that can be included are:

  • Conformal coating
  • ITAR
  • Restriction of Certain Hazardous Substances
  • Lot tracking

Inspection Requirements

Besides PCB testing, any other inspection requirement by the PCB has to be shared.

Some of the inspection techniques offered by various Contract Manufacturers include Flying Probe Tests, X-rays and Automated Optical Inspection (AOI).

Most PCBs have to reach a certain standard during manufacture be it IPC-regulated or Industry specific.

The Contract Manufacturer should be informed early enough of the standards required to be met by your PCB.

Quantities And Release Sizes

The exact details of the quantities of PCB and their release sizes should also be included. Such information includes;

  • Order quantity
  • Delivery date of the first PCB batch
  • Amount of PCB product you intend to purchase in the following 12 months or the approximate annual usage.

What Is A PCB Contract Manufacturing Agreement?

This is a document that defines the legal relationship between the PCB seller and the manufacturer producing the PCB.

It states all the aspects of the production process and each party’s responsibility.

These aspects widely vary depending on the capability of the manufacturer and the requirements of the seller.

Issues that have to be agreed on in the agreement include but not limited to;

  • The delivery timeframes
  • Design responsibility and other production elements
  • The number of PCB products anticipated for delivery

The Agreement also outlines quality expectations and the acceptable structures of supply chain. It gives guidance on the steps to be taken in the event of a dispute that would normally have;

  • Responsibilities when the dispute is being handled
  • Chances of solving it using mediation
  • Contract termination point

What Are The PCB Testing Methods Contract Manufacturer Use After Completing An Order?

Reputable Contract Manufacturers always offer a range of PCB testing processes. These testing methods are very vital in the PCB manufacturing process.

X-ray Inspection

This inspection is also known as the AXI. It is more of an inspection tool for most Contract Manufacturers.

An X-ray technician is able to detect flaws promptly during this test by viewing the barrels, internal traces and the PCBs solder connections.

Elements that are normally concealed from sight can easily be checked by X-ray testing.

Automated Optical Inspection (AOI)

Photos of the PCB are taken either by a two 3D cameras or a single 2D camera.

A comparison is then made between the PCBs detailed schematics and its photos from the cameras.

If a schematic doesn’t match the boards photos to a certain degree, then an inspection technician flags the board.

Issues can be detected in advance using AOI to ensure immediate shutdown of production.

However, the board is not powered by the AOI and does not have total coverage of all the part types.

Automated Optical Inspection Test For PCB

Automated Optical Inspection PCB Testing Method

In-circuit Testing / Bed-of-nails Test

This is the most vigorous PCB testing type present.

It is very expensive but the cost depends on fixture size, the board among other factors.

The individual board circuitry is powered and actuated by the ICT.

This test is usually 85-90% human error-free.

Bed Of Nails PCB Test

Bed Of Nails Test

Burn-in Testing

This is a very extreme testing type for PCBs. Its purpose is to notice initial failures and find the load capacity.

The strength of burn-in testing normally destroys the parts being tested on the PCB.

This type of test usually shortens the PCBs lifespan especially if the boards rated stress is exceeded.

The testing limit is reduced if a few or no failures are found after a brief period of time to evade over-stressing of the PCB.

Flying Probe Test

This test option is less expensive compared to in-circuit testing.

This test is non-powered and checks for diode issues, opens in the PCB circuit, capacitance, shorts, inductances and resistance.

This test uses a probe with needles attached to it on an x-y grid gotten from Computer Aided Design.

The contract manufacturer has programs that synchronize to equal the PCB for the program to run.

 Fly probe PCB Testing

Functional Testing

Some customers have a preference of the old-functional test. The Contract Manufacturer utilizes this to confirm that the PCB will power up.

Requirements for this test include;

  • External equipment pieces
  • Requirements for industry standards
  • Fixtures

The customer normally provides the functional test and any other parameters used.

Some Contract Manufacturers can assist in developing and designing this kind of test.

This may not be a preferred choice if the PCB product needs to get out of the manufacturer quickly because it takes a lot of time.

But for purposes of longevity and quality, this test saves money and saves the company’s face.

What Are The Advantages Of Contract Manufacturing For PCBs?

Some of the advantages include:

Accurate Cost Estimates

Contract Manufacturing enables one to know the exact amount one should put aside in their budget for the whole PCB manufacturing process.

A detailed estimate of the cost is given up-front.

Unexpected delays or costs are less likely to occur since the contract manufacturer knows the projects exact cost.

They also know the amount of time taken at each stage based on their experience with past projects.

High Quality Products

Contract Manufacturers have the required technology and expertise to create excellent PCB products.

The skills of expert engineers are applied combined with advanced equipment.

The PCB end product will be efficiently functional and better than own creations.


Contract Manufacturers usually negotiate viable for raw materials in bulk thus increasing production but at a minimum cost.

Production is thus scaled up without incurring more costs.

They also maintain a comprehensive log of the customer’s preferences in PCB manufacture. This enables them to rapidly scale the production up or down when the need arises.

Reduced Cost

There is no need to pump capital on infrastructure, PCB designers and other skilled manpower.

The overhead costs are greatly reduced thereby increasing the return on investment (ROI).

Industry-specific Solutions

Experienced Contract Manufacturers have a variety of specialized skilled professionals who ensure a niche is found with innovative design results.

Contract Manufacturers for specific PCBs can easily be found and they can refine designs due to heir years of experience in the same field.

Faster Time-To-Market

Due to the availability of advanced manufacturing equipment and experienced staff, Contract Manufacturers can create PCB products very fast.

The PCB product can find its way to the market within a very short time.

What Are The Cons Of Contract Manufacturers For PCBs?

Some of the limitations include:

Difficult To Find Efficient Provider

Without researching properly, one could end up sourcing the wrong company.

Thorough research and vetting needs to be done in order to find the most appropriate Contract Manufacturer who fulfills the precise needs.

Unreliable Contract Manufacturers may take time and deliver faulty PCBs.

Loss Of Control

The Contract Manufacturer normally takes full control of the process of manufacturing PCBS. Critical knowledge around production techniques may be lost in the process of relinquishing control.

Problems cannot be troubleshot in production if there is no supervision.

Significant points of the PCB project should be properly assessed after production.

Intellectual Property Risk

Intellectual property may be stolen since outsourcing a Contract Manufacturer means very many people will have access to the intellectual property.

It may be leaked and used or misused elsewhere.

The contract manufacturer may also potentially be your own competition using your intellectual property or modifying it.

Communication Gap

Poor communication between a Contract Manufacturer and client may cause a variety of problems like;

  • Unrealistic timelines
  • Capacity qualification misunderstandings
  • Transition plan not set

What Is The Cost Model For A PCB Contract Manufacturer?

Contract Manufacturers use the ‘cost-plus’ model to bill their clients.

This means that they give an approximation of how much it will cost to manufacture a PCB including materials and manpower to satisfy the requirements.

The contract manufacturer’s profit margin is then factored in to bring a total sum that is submitted to the client.

The client then decides if it is viable to contract out the PCB production or retain producing on their own.

With mass production, it will make sense to contract out due to the contract manufacturers specialist workforce and their accessibility to bulk materials.

What Is The Importance Of Contract Manufacturing PCBs?

Firms have various reasons for utilizing Contract Manufacturing although the most important reason is always to reduce cost.

Contract Manufacturing allows firms with little great economies of scale and low overhead costs to be used by organizations for their PCB manufacturing.

However, besides cost, other different reasons for Contract manufacturing include access to advanced technology, a favorable return on resources, faster lead times and many more.

Just like any other business decision, contract manufacturing involves both risks and chances and they must be weighed to make an informed decision.

Is The Intellectual Property At Risk When Using A Contract Manufacturer For Your PCB?

Intellectual property may be stolen since outsourcing a Contract Manufacturer means very many people will have access to the intellectual property.

It may be leaked and used or misused elsewhere.

The contract manufacturer may also potentially be your own competition using your intellectual property or modifying it.

How Does Contract Manufacturing Of PCBs Maximize Profits?

This is the greatest advantage of contract manufacturing, maximizing profits.

A firm has time to focus on other tasks by outsourcing a contract manufacturer for its PCB manufacture.

It would take a firm ages to match the competence and skillset of accomplished contract manufacturers and not mention the capital investment involved.

Under contract manufacturing, a firm outsources its production process to contract manufacturers.

Such manufacturers are highly skilled and with advanced production technologies.

They manufacture very high quality PCBs with decreasing expenses.

This ensures a firm delivers high quality products to their customers.

What Are The Forms Of Contract Manufacturing Of PCBs?

They may include:

  1. Using the equipment and facilities of the Contract Manufacturer
  2. Producing parts of an end product
  3. Full-scale production
  4. Contracting manpower

Who Can Use Contract Manufacturing Of PCBs?

Contract Manufacturing is widely applied in many industries and different sizes of business. Large companies usually utilize this especially in the electronic industry where it has become an integral part of the workflow.

On the other hand, startups also use contract manufacturers to produce PCBs in large volumes that they lack the ability to support.

Contracting out the PCB manufacture allows the startups to scale without necessarily capitalizing in a factory.

Or, investing in the manpower and machines required for PCB production.
