What are solder pads?
A solder pad is the part of a printed circuit board — or PCB — that supports the pins of components like transistors and chips. Typically, when devices break or components are removed from PCBs, it can result in damaged and missing solder pads.
What causes a circuit board to fry?
Boards might burn because of poor protections. The lack of properly sized fuse protection should be number one priority. A high voltage protection diode protects the board from burning in the event of a lightning strike or other voltage surges. Other reasons for board burning are related to technician error.
How do you know if a circuit board is fried?
Physical Damage Smelling smoke or seeing charred circuitry are obvious signs, but also examine the capacitors, which are cylindrical in shape and placed in various locations on the board. Their job is to filter the electricity going to various components on the board, and power surges or overheating can damage them.

What to do if a capacitor leaks?
If leaks, cracks, bulges, or other signs of deterioration are evident, replace the capacitor with an equivalent type and voltage rating. Capacitors have a limited life and are often the cause of a malfunction. Look for broken leads on the components.
Why are my circuit boards not working?

Why is the methodical use of relevant test tools important?
The methodical use of relevant test tools helps investigators to identify the cause of failure quickly and accurately, and thereby speed up PCB repair.
What is V/I testing?
If a board can’t be powered up safely, then power-off testing such as V/I and Signature testing can be performed. V/I testing (also known as Analog Signature Analysis) is a technique which is excellent for fault finding on PCBs, and is ideal when diagrams and documentation are minimal. Analog signature analysis can be done with instruments such as ABI Electronics’ System 8 ATM Advanced Test Module (refer again to Figure 5 ).
What are the instruments used to test a circuit?
Typical benchtop instruments: LCR meter, oscilloscope, DMM, and spectrum analyzer. The most versatile tool is the multimeter, but depending on the complexity of the PCB, an LCR meter, oscilloscope, power supply, and logic analyzer may also be needed to investigate the operation of the circuit.
Is automated repair cost effective?

Our PCB repair services and the team can help you reassemble or repair the damaged circuit board to make it close to its original state.
How to repair electronic circuit boards?
The electronic circuit board repair is most commonly after thermal and physical damage and excessive voltage to the components. So, how to repair broken circuit boards step by step?
What happens if a PCB is overheated?
If a PCB is overheated the most likely outcome is that the copper layer will de-laminate from the fibreglass board. This usually leads to broken joints and a non-working circuit. It is possible to repair some faults using adhesive copper tape and solder. Ask Question.
What is a PCB made of?
Printed Circuit Boards (PCB) are made from layers of fibreglass and copper, glued together. Whilst the glues used are very heat resistant it is possible to overheat a PCB and damage it. Kitronik PCB designs use large tracks and pads to help make this a rare problem, the larger amount of copper helps to dissipate the heat.
How to get solder resist off PCB?
Scrape a little of the solder resist off with a knife, sharp screwdriver or fine sandpaper. Ensure that the exposed track is clean and shiny. It is also a good idea to clean any residual burnt PCB material off, to allow the tape to stick well.
Does copper tape melt?
Carefully solder the joint (s) where the repair has taken place. Most copper tape adhesive melts at soldering temperatures, so be quick and use as little heat as possible. When the tape cools the adhesive will usually remain sticky.
Can copper tape be cut?
The Copper tape can be cut to size with scissors, craft knife etc. Once a repair has been made it is also possible to trim the excess tape. If this is done exercise caution, as the repair is more fragile than the original PCB track, and may become unstuck again.
What is the substrate for PCB?
It may call for copper or silver to be reseated to repair trace pathways. PCB substrates are often comprised of fiberglass or an epoxy resin with copper foil bonded to the conductive layer.
What causes PCB failure?
1. Physical Damage. This is the more obvious choice when it pertains to the damage of a circuit board. In fact, the most common causes of PCB failures all stem from physical damage to a device or its internals. This can be just about anything pertaining to physical pressure or shock.
What is a PCB in a coffee maker?
Everything except the simplest of electronics uses a board of some kind to connect and mechanically sync all elements of the product. A coffee maker, for instance, might have a small PCB inside to connect the electronic control system, heater element and display.
What are PCB components?
Those “components” include things like the battery, resistors, LEDs, transistors, capacitors and more. Boards are often produced in layers, which include various levels of conductive and non-conductive sheets.
How do PCBs work?
Today, it’s all done via design and manufacturing software. PCBs are mechanically necessary to support and connect all components within the device, which are synced using conductive tracks—this allows electricity to flow freely through the board and from component to component.
What is a power meter?
Whatever the case, a power meter can be used to test each individual component and the general conductivity of the board. How to Diagnose and Repair. All professional repair teams have a power or voltage meter that can be used to identify electrical issues with a board and its components.
