Water Damage Repair on Your Samsung Galaxy S with an Ultrasonic Cleaner

Sleekly designed, the Samsung Galaxy S mobile phone offers cutting-edge features. The Galaxy S has a 4.0” Super AMOLED display for easy viewing and touch screen operation. Integrated with Swype technology, the smartphone also features a camera phone, DLNA connectivity, and HD video recording (720p). To keep your Android phone in its best condition, it’s important to regularly maintain the unit. One of the best ways is to clean your printed circuit boards (PCBs) with an ultrasonic cleaner.

Samsung Galaxy S units can take a lot of abuse including being left out in the rain, dropped in the soup or otherwise rendered inoperable. Unless your Samsung Galaxy S is irreparably damaged, it can most likely be restored to operation in an ultrasonic printed circuit board cleaner. With the same technology used by printed circuit board manufacturers, ultrasonic circuit board cleaning quickly and safely removes contaminants from the delicate components in your Samsung Galaxy S.

Here you will learn:

  • How an Ultrasonic PCB Cleaner Works
  • How to Select and Set Up your Circuit Board Cleaner
  • How to Disassemble, Clean and Reassemble your Samsung Galaxy S

How Ultrasonic PCB Cleaners Work to Restore Your Samsung Galaxy S

Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination by using the power of cavitation action. This is the term used to describe the implosion of billions of minute bubbles contacting Samsung Galaxy S PCB components and surfaces. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

When the bubbles implode contaminants are quickly and safely removed from PCB surfaces without damaging delicate parts. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes that might lodge dried residue, dust and dirt particles. The ultrasonic PCB cleaning system will complete the job in as little as 10 to 15 minutes. And it will do it in an environmentally friendly manner because the ultrasonic circuit board cleaning solution formula is a biodegradable concentrate that minimizes disposal problems.

How to Select and Set Up your Samsung Galaxy S Circuit Board Ultrasonic PCB Cleaner

Ultrasonic PCB cleaners come in a variety of sizes from bench top units to a floor-mounted industrial ultrasonic cleaning machine, so you can select any size you need. Our most popular models for cleaning Samsung Galaxy S circuit boards are the ¾ gallon Elma EH075EL and 1½ gallon Elma EH150EL. You should select an ultrasonic PCB cleaner equipped with a frequency sweep function, such as an Elma model, to prevent damage to sensitive components during cleaning. Choose a model also equipped with a heater to improve the ultra sonic cleaning process.

Whatever the model and size of ultrasonic circuit board cleaner you use there are steps to take before cleaning begins.

  1. Fill the ultrasonic cleaner tank to the fill line (or approximately 2/3 full) with ultrasonic cleaning solution such as Elma tec clean A1 diluted 1:20 with water.
  2. Turn on the ultrasonic cleaner, set the heater to approximately 50°C, and operate for about 30 minutes to drive off cavitation inhibiting entrained air. Degassing is complete when bubbles stop coming to the surface and must be performed every time the tank is filled with fresh circuit board cleaning solution.

How to Disassemble, Clean and Reassemble your Samsung Galaxy S

Step 1: Disassembling your Samsung Galaxy S

With an opening tool or a fingernail, remove the battery cover. There is a small groove at the bottom of the unit you can use to pull the cover off with. Next, you will need to pull out the battery of your Samsung Galaxy S. In order to get to the main board, there are six screws that need to be removed.

Once the screws have been removed, use the same case opening tool and pry the front LCD display from the back case. Be gentle with this. After removing the front display, you will notice that there are six connector tabs that need to be removed. You may use your case opening tool again. Another important step is to remove the white antenna cable found on the right side of the phone.

Two screws hold the circuit board down. Remove them and pry the circuit board off from its compartment. You will then need to remove another small screw which holds the headphone jack. Pry the speaker out as well being careful not to damage it. You will need this to remove the circuit board of your Samsung Galaxy S. Once done, the circuit board can be pulled off the phone.

You now hold in your hand, your Samsung Galaxy S circuit board.

Congratulations! You have successfully removed your circuit board from your Samsung Galaxy S! You may now proceed with the next step.

Step 2: Cleaning the Printed Circuit Board

Set the ultrasonic cleaning equipment's thermostat to 50°C and activate the Sweep mode. While the solution is heating, place your PCB in the basket. If you are cleaning more than one at a time take care that they do not touch each other. Once the operating temperature is reached lower the basket into the cleaning solution and set the timer for 10 minutes. Cleaning time depends on the condition of the PCBs and may have to be adjusted.

At the end of the cycle remove the components from the bath. If they are not clean replace them in the bath until the cleaning is complete. Then rinse them in distilled or deionized water to remove all traces of the cleaning solution and avoid water spotting. Dry them with an air blower or warm air dryer.

Safety note: DO NOT reach into an operating ultrasonic bath. Instead remove the basket if you want to inspect or rearrange the parts.

Step 3: Reassembling your Samsung Galaxy S

First, it is important to return the circuit board to its original position in your Samsung Galaxy S. Secure the speaker once again, making sure you don’t damage it. Try to use just the right amount of pressure when doing this. Next, return the headphone jack as well by screwing it in place. Once both parts are secure, you may now return the two main screws holding the circuit board down.

Reattach the white antenna cable found on the right side of your Samsung Galaxy S phone. Use the case opening tool if you find it hard to do so with your fingers. The six connector tabs you removed must be returned as well. Once this is done, you may now attach the front LCD display to the back case.

After the back case is connected, you must now return the six screws to the phone itself. Make sure these are on, tight. Return the battery by simply popping it in. Shut the battery cover until you hear a click sound indicating that the cover will not budge. Make sure that nothing jiggles when you lift your smart phone.

Admire the piece of work you just put back together.

Voila! Start your device and your Samsung Galaxy S should be good to go.

More Operating Tips

Any contaminants that rise to the surface of the bath should be skimmed off and disposed of properly. When the circuit board cleaning solution becomes discolored or cleaning takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove any material that settled to the bottom of the tank. Clean the ultrasonic machine using a cleaning process recommended by the manufacturer.
