Microsoldering – What Is It?
Here at Techcycle we don’t just fix screens and replace batteries on educational devices. We also offer a rare brand of services that can help electronics suffering from board level issues get back to life again – that’s microsoldering. What is it, you might ask?
Microsoldering is a form of soldering components that have traces and pads barely visible to the naked eye. A steady hand is required to place components on boards when a robotic machine is not available. Other must have precision tools include a 10-20 times magnifying microscope, fine solder tips, and heat air gun tools with small nozzles. Sometimes confused with welding, soldering is done at lower temperatures to prevent damage to fragile components on computer boards. This also allows the service time to be more flexible and precise so that chips can bond properly to the copper and gold traces on the board.
When It’s Needed
When simple part replacements won’t get the device back to full working order, a board repair service may be needed. Unfortunately, processes for board manufacturing are not always perfect. While devices go through a boat load of tests to ensure they leave the factory working, certain features can fail over time or break under extreme conditions. Most of what we do in the microsoldering department is based on prior experience with other similar issues. We use specialized schematics and board views that help us map out what the root cause of certain problems may be on the board. Let’s take a look at the ten most common issues we’ve seen on our work bench:
- No Backlight/Display
- Water Damage Repair
- No Audio
- No Touch
- Data Recovery
- No Power
- Port Replacement
- No Camera Response
- Fingerprint/Face Biometric Sensor Failure
- Bootlooping/On Board Storage Failure
What Can You Microsolder?
While most of our board repair services are for mobile devices, desktop computers and video game consoles, we have also been known to branch out into other electronics. Hobby electronics such as drones, boards for home appliances, and even a board controller for an electric wheelchair have been successfully repaired here.
The Future of Microsoldering
I do not see the demand for these specialty services slowing down any time soon. The race to make handheld devices smaller and more powerful is accelerating beyond the scope of our imagination. Enhance the services and products you provide in your shop or technology department by considering us as a repair partner.
