PCB Repair and Refurbishment

Air Conditioning Controllers

In PCB Repair and Refurbishment, and over 20 years ago Greasley’s were asked to repair a large batch of ‘Trend’ Controllers. However, this isn’t normally a job for an air conditioning company and it certainly can’t be repaired on site. Repairs need to be carried out in a sterile clear environment with specifically trained repair specialists who know what to look out for and have the appropriate test equipment to hand.

A prime example of these repairs are hospital air conditioning repairs. We are already helping in some parts of the UK and would like to help the NHS more all over the country and save them thousands!

Here is an example of a I2920 Andover air conditioning controller being repaired.

We also repair many other air conditioning controllers including Trend IQ, Cylon, Mitsubishi controllers, Daikin, Sanyo air conditioning units and various others including boiler controllers. Sanyo air conditioning unit repairs are really common in the winter months as they are usually located outdoors and on a roof and not used as much unlike the summer months.

Power Suppliers

Power Supply Repair is possible and can also be fairly inexpensive, the majority of our customer’s have problems with expensive Pcb’s mainly caused by a BAD Power supply. It is a known fact that the life of a capacitor is relatively short compared with other electronic components, and therefore the life of most Power Supplies depend on the capacitors.

Greasley Electronics Ltd have developed relationships over the years with many Power Supply Manufacturers and designers so we are able to offer quick replacements where we can. Greasley’s may repair their existing unit, timescales normally 20 – 25 day turnaround and then give them a “back up” Power Supply.

Finally, we encourage everyone to take care of their existing Power Supplies, check the fan is running and have it serviced regularly (replacement of Capacitors etc) as this will extend the life or the machine and other Pcb’s it provides power to.

Industrial Computers

Industrial computer repair down to component level are carried out using the state of the art diagnostics, soldering and inspection systems.

A very common failure we are experiencing is in the in production of the motherboards. If poor solder has been used in the BGA’s, they give intermittent boot up failures.

Programmable Logic Controllers

Using the latest techniques damaged PCB tracks and trough – plated holes can be remade by our expert staff often allowing even the most damaged of circuit boards to be returned to service.

Using failure pattern analysis our technicians are able to notify clients of any failure trends and, if requested replace all ”at risk components” as part of the standard repair package. Final test procedures, packaging and shipping requirements are always agreed with the client as part of the industrial electronic repair.

Since today’s circuit board repairs are more sophisticated than ever before, we use the latest procedures and technology we are able to offer PCB Modification and final test and assembly.

Knitting Machinery

In addition to the sewing machine industry, knitting machinery, although not made in the UK we can still repair and refurbish machines from all over the world.

Greasley Electronics have been repairing and refurbishing knitting machines for over 30 years so we have experts in this field!

Aerospace

We provide specialist aerospace electronics repair and refurbishment services for a wide range of aviation and flight control systems. We support manufacturers, maintenance teams, training facilities, and system integrators by offering a reliable and cost-effective alternative to replacement.

Our engineers carry out component-level fault diagnosis and PCB repair, allowing us to restore complex aerospace electronic assemblies that are often deemed beyond repair.

We regularly repair and support:
• Engine management and control systems
• Flight simulator electronics
• Flight deck controllers and cockpit interface boards
• Power supply and control modules
• Signal processing and communication PCBs
• Input/output boards and automation controllers

All repairs include a full inspection and component-level testing. Where possible, units are tested on dedicated rigs or simulated environments. Final functional testing is completed in the end application by the customer, ensuring system compatibility.

By choosing Greasley Electronics, you benefit from:
• Reduced equipment replacement costs
• Extended service life of critical electronics
• Shorter downtime
• Support for legacy and obsolete boards
• Environmentally responsible repair solutions

We work to the highest standards of quality and reliability, helping aerospace

Robotics

Experts are needed to fix the circuit boards within the units. These are cutting edge machines that are constantly on the production line. Modern warehouses depend on complex electronic systems and robotics that are expected to run continuously, often well beyond their original design life. As equipment ages, components become harder to source and OEM support can diminish, making full replacement costly and disruptive. Our specialist electronic and robotic repair services help warehouses extend the life of their existing assets by diagnosing faults at component level, repairing obsolete or hard-to-replace parts, and restoring equipment to reliable working condition. This approach reduces downtime, avoids unnecessary capital expenditure, and keeps critical warehouse operations running smoothly without the need to replace entire systems.

Anything Industrial Electronic

Electronic repair ( PCB’s ) is more complex today than ever before, but despite how severely damaged they may be, they can be repaired! Circuit board repair is our speciality.

Also the high value of many Printed circuit boards demands that they be repaired? Even less expensive assemblies require repair because you may require a quick turn around?
A few years ago, Printed circuit boards were much simpler and repairs were relatively easy.? Today’s PC boards have fine pitch components, ball grid arrays and fine line circuits making them a challenge to repair. However now we are driven by simple economics and must repair damaged Printed circuit boards whenever possible. Greasley Electronics repair pcb’s that might otherwise be consigned to scrap.
