When your phone goes wrong, we know the rework station are essential tools for phone repair. The rework station can used to remove/replace CPU/BGA /ICS from cell phone,which is the removal of solder and components from a circuit board for troubleshooting, repair, replacement, and salvage. If you want to work better with rework station, you need to know the following tips.
Considerations for use: 1. when you heating the CPU/BGA, you must control the temperaturn, usually it is between 300 degrees to 400 degrees. If it is an analog one having no indicator or display having just knobs, the knob of heat is kept on 3.5 setting. 2. you must carefully to setting the air, usually it is kept on a litter above the minimum.If more air is used, it may damage or remove the neighboring parts and if no air is used, it may lead the coil inside the handle to burn. So you have to keep it to a setting so that a little bit of air is coming out along with the heat. Both of this need to base on your job and the situation, and then ou choose the best one for your job.
The related tools: 1. solder flux: it is applied at the edges of the IC before heating or removing an IC in order to PCB BGA paint prevent corrosive arcing. 2. solder wick: it is a phone motherboard repair connection cables, also widely used in electrical and electronics, solder parts like circuit board, electronics devices and others. 3. solder iron 4. Tweezers Repair Process : when you are ready for everything, you need to turn on the rework station, move its handle such that the tip where the heat comes out in a circular motion inside the edges of the IC. If you just want to heat IC, keep moving 2 to 3 times. If you want to replace it, keep on moving till the IC loosens from the board and then lift it with tweezers.
Matters need attention: 1. Do not try to pluck it out forcefully if it hasn't loosened as it may damage the points below on the board. 2. If you are not professional, it's better to practice on broken circuit boards and see more videos of professionals on youtube before you start to work. 3. Recommend a 3-IN-1 Infrared BGA Rework Station: SMD Hot Air Gun + 540W Preheating Station + 75W Soldering Irons,it's good for professional repair staff,if you want more information visit here.
