Tips And Tricks For Using A Heat Gun

When going to the CPU, remove the nozzle of the air gun, adjust the temperature of the heavy duty hot air gun to 6, and adjust the air volume of the heat gun to 7-8. When the actual temperature is 280 degrees -290 degrees, the height of the heavy duty hot air gun nozzle from the CPU is about 8cm. Master, such as the 3508 CPU, blows the air gun obliquely on the four sides of the CPU and tries to blow hot air under the CPU so that it is easy to blow off the CPU intact.

Motherboard disconnection processing method

Most of the motherboard disconnection and drop points are caused by improper operation. The glued CPU is likely to be broken and dropped under the motherboard due to improper operation. I will introduce my own experience of removing the glued CPU to everyone, the heavy duty hot air gun The temperature is adjusted to 5.5. The scale air volume of the heat gun is adjusted to 6.5-7. The actual temperature is 270 degrees -280 degrees. Blow straight up and down to the CPU. Everyone knows that the sealant of the CPU is generally soft after being heated, such as 998 Samsung Philips Philips After being heated, the glue will be softened. First, heat the glue around the CPU and clean it before moving the CPU. When heating the CPU, make sure that all the tin under the CPU is melted. When the CPU is started, there will be no disconnection and drop points. , Whether you want to put the sealing tape on the motherboard or the CPU, you can do it yourself, Use a flat shovel screwdriver to do it yourself, that is, use the steel plate of the tin plate that you use as the material, and cut it to 2CM width. Just sharpen it like a knife blade. Use a special tool to clamp it. When you melt the tin under the CPU, you insert your tool under the CPU. If you want to put the sealing tape on the CPU, you can put the tool along the motherboard. Plug it in. If you want to put the sealing tape on the motherboard, you can just insert the tool along the bottom of the CPU. Do you know why there are disconnections and dots? It’s because you didn’t even heat most of it during heating. The tin under the CPU has melted and a small part of the tin has not completely melted. Everyone has paid attention to why the broken wires and dropped spots are on a small piece of the motherboard. There are no broken wires or dropped spots on other large motherboards. You did not evenly heat the CPU when using the air gun.

Desoldering

It is enough to control the heat and air volume of the heat gun like some bells and power amplifiers.

Blow welding

Blow-welding CPU is often short-circuited when replacing a new CPU or other BGA ICs. Why do short circuits sometimes occur? My experience is mainly in changing the position of the motherboard BGA IC when blow-welding CPU or other BGA ICs. Next, clean the IC with the flux applied. The most important thing is to pay attention to the position of the IC on the motherboard. The IC automatically positions you when the CPU or other BGA ICs are not blown. I don’t know if it’s misplaced, so pay attention to the position of the IC on the motherboard. Use a heavy duty hot air gun. The air volume should be small. The temperature is 270-280 degrees. You can set it by yourself. You have to pay attention to the soldering of the IC. Whether the solder ball is large or small, it is necessary to pay attention to the IC's moving range when the solder ball is large, so that it is not easy for the solder balls under the IC to roll together and cause a short circuit. The IC's solder ball is okay to have a small moving range.

Possible glitches of the Compact Corded Heat Gun

Compact corded heat guns, like any other electrical appliances, can experience glitches or issues over time. It's essential to be aware of these potential problems to ensure safe and effective use of the tool. Here are some possible glitches or problems you might encounter with a compact corded heat gun:

Overheating: Compact heat guns can overheat if used for extended periods at high temperatures. Overheating can lead to damage to internal components and affect the tool's performance. To prevent this issue, always follow the manufacturer's guidelines for temperature and duty cycle recommendations.

Burned-out Heating Element: The heating element inside the heat gun can burn out due to prolonged use at high temperatures or power surges. When the heating element fails, the heat gun will no longer generate heat. Replacing a burned-out heating element can be expensive and may require professional servicing.

Power Cord Damage: The power cord of the heat gun may become damaged over time due to bending, twisting, or exposure to heat. This can lead to electrical shorts, intermittent power supply, or complete loss of power. Inspect the cord regularly for signs of wear and tear, and replace it if necessary.

Trigger or Switch Issues: The trigger or switch that controls the heat gun's operation can become faulty. This can result in difficulties turning the heat gun on or off, or it may cause it to become stuck in one position. It's important to ensure the trigger or switch is functioning correctly for safety and control.

Noisy Operation: Some heat guns may develop noisy operation due to issues with the internal fan or motor. Unusual or excessive noise can be a sign of worn-out components or improper lubrication. Regular maintenance and lubrication can help prevent this issue.

Inconsistent Temperature Control: Compact heat guns are equipped with temperature control settings. If these settings become inaccurate or if the temperature fluctuates unexpectedly, it can lead to problems with precision heating for specific tasks. Ensure that the temperature control mechanism is functioning correctly.

Cooling System Problems: Heat guns rely on a cooling system to prevent overheating. If this system fails, the heat gun may become too hot to handle safely. Regularly check for blockages in the air vents and ensure that the cooling system is working as intended.
