AOI Automated Optical Inspection

Automated Optical Inspection (AOI)

“High Quality is Always at the Top of our Agenda” – Continuous Improvement Drives Makar’s Manufacturing Quality & Reliability


As part of our PCB assembly process, we operate in-line Automated Optical Inspection (AOI) on all of our production lines. AOI enables fast and accurate inspection of electronic assemblies, in particular PCBA’s, therefore ensuring optimum workmanship quality.


What is AOI and what does it inspect?


These advanced inspection machines can fully inspect a densely populated PCB Assembly in a matter of seconds, carrying out:


Component Inspection Tests
  • Checking for missing, reversed, shifted, damaged, skewed, and tomb stoned components.
  • Checking polarity and marking of components (identifications, signs, colour etc)


Solder Inspection Tests
  • Checking for no solder, insufficient/extra solder, solder bridging and flux deposits.


It’s an extremely powerful solution to quickly identify defects and ensure the highest quality of our manufacturing process. Our In-line AOI systems are placed just after our reflow process on our surface mount lines.


One of the key elements of an Automated Optical Inspection system is the image capture. The high resolution camera system takes an image of every component. This is then analysed by complex algorithms searching for the defects mentioned above.


Before processing all boards through the AOI, we pass a “Golden Board” through so that the system can learn the relevant attributes. This “Golden Board” is a known working board which has passed functional testing and a First Article Inspection.


Based on the golden board, differences, abnormalities or even errors can then be clearly indicated by the AOI’s built in processing software. We record all results for PCBs in a database, which we can then analyse in-depth.


So,  how does this benefit our customers?

  • Zero/extremely low defect quantity, resulting in high quality, consistent output for our customers
  • High pass rate for functional testing, therefore improving efficiencies and reducing customers testing downtime.

The Wave Soldering Process

The Wave Soldering Process – 5 Key Steps

Supporting our surface mount pick & place machines, we operate in-line hand assembly conveyors ahead of the wave soldering process.

Our hand assembly team can fit all PTH (Thru Hole) components at high speed. We have an automated masking process to protect the areas which don’t require solder. Any open thru-hole via’s will also be spot masked before processing the populated PCB’s through wave soldering.


How does this benefit our customers?

  • Very competitive pricing as a result of high production efficiencies
  • High quality and consistent solder joints
  • High volume production capability
  • Fast turnaround assembly


So, how does the wave soldering process work?

Wave soldering is an in-line process that follows surface mount, reflow and AOI.  The underside of the PCB (Printed Circuit Board) is treated with flux before being preheated and then immersed in liquid solder.


The 5 Steps of the Wave Soldering Process


Step 1 – Set Up

The wave soldering machine combines a tightly controlled flux application, pre-heating and heated solder bath process. The bath holds between 300-500kg of solder which is kept at the required level by our trained operators. Once the machine reaches the pre-set solder profile levels, then the automated process can commence.


Step 2 – Placement of the PCB

Once the machine is ready, the PCBA can be processed from the hand assembly station through the machine. There are metal clasps on the conveyor which hold the board firmly in place as it goes through the following stages.


Step 3 – Cleaning the Components (Fluxing)

During this crucial step, the machine thoroughly cleans components to remove any metal oxide layers which may have formed using the flux application process. Flux is a chemical cleaning agent and is sprayed on the PCBA before the solder is applied.


Step 4 – Application of Solder

The PCBA is passed over a bath in which a pump produces an upwelling of solder, which resembles a standing “wave”. Our team pre-set the timing/speed of the conveyor, ensuring that sufficient time is allowed for the solder to settle on the joints and ensure strong joints are formed.


Step 5 – Cleaning

This is the final step in the wave soldering process. We wash and clean our circuit boards through our chemical wash plant, as well as hand cleaning with the help of deionised water and IPA. Flux residues can form on the PCB during the machine process and will be removed during this step.

Conformal Coating

High Performance Conformal Coating

Conformal coating is a thin polymeric film applied to a printed circuit board (PCB) which protects the board and its components from the environment and corrosion.

Our latest showcase, as part of our growth and investment plan, is our new High Performance 4 Axis Selective Coating Machine with a UV Curing Oven.

This allows us to coat PCB Assemblies at high volume, while maintaining a repeatable accuracy of 0.05mm.

Features include:

  • Tilt able valves with ±180 degree rotation, allowing side coating for components
  • A mix of high precision valves for coating in tight/shadowed spaces
  • Rapid UV curing (less than 1 minute to cure a PCB)

So, how does this work?

We program the automated conformal coating robot for each product we are coating. This removes the time consuming, manual process of masking non-coated components. In turn, we are able to offer competitive pricing and fast turnarounds on coated PCB Assemblies.

Our team can offer conformal coating as part of our PCB assembly service, or as a service in it’s own right.

Please take a look at our PCB assembly and product assembly pages for more information on our capabilities.

Printed Circuit Board

The Printed Circuit Board

Makar Technologies featured in this months edition (February) of the Knock News magazine, with a captivating article based around the printed circuit board.

Knock News is an independent local magazine that is ‘quirky and original’, founded by David Gordon in 2007.

We welcomed David and Richard Oakley, the author of the Makar Technologies article, into our factory for an insightful view on our innovative developments.

The article goes into fine detail of some of the internal processes used to build a printed circuit board, as well as providing an overview of electronics design and manufacture in general. 

Makar Technologies Ltd currently has a full order book and was working on projects to remotely control caravans and a stair-lift during our visit, Dave King says that if you require a system to be controlled, they can also provide the control electronics, actuators and computer systems to bring the project to life. They are what industry describes as a ‘turn-key supplier’, they do everything simply leaving the customer the starting key. Customers can have systems designed with or without any specification in mind. The Makar design team would then look to generate PCB designs, giving costing, functionality and future proofing suggestions before negotiating with the client the final design. This may or may not involve building prototypes for the customer’s approval. Makar’s engineers are capable of writing software for controlling system operation, for example, the firmware to control the speed and torque delivery of an electric motor. Makar are also currently looking to increase the functionality of their equipment by building smart intelligence into the equipment.

For a better understanding of our industry, we would highly recommend taking the time to read the knowledgeable article which can be found below:
