Use skill and method of hot air gun
Use skill and method of hot air gun
(a) when you blow a power amplifier with a plastic cover, you will often blow the plastic cover of the power amplifier out of shape or burn out. 5110 the temperature of the heat gun turned to the scale of heat gun air volume is set to 6.5-5.5 7 actual temperature is 270 degrees - 280 degrees (according to their own heat gun) removal lon-izing mouth from 8 cm is the height of their mastery of the power amplifier, power amplifier of edges (because the metal thermal conductivity fast soon melted tin) heat so quickly into the lower part of the power amplifier power amplifier the down the intact, in welding new kung fu with blower gun to the mainboard first heating heating when the tin melting under the main board in put power amplifier in blowing around the kung fu with respect to OK! You will be a very simple is their usual use of air gun did not pay attention to ah!
(2) to the CPU the QiangZui blower gun are removed, the temperature of the heat gun to the scale of 6 heat gun air volume transferred to the 7-8 actual blower gun mouth when the temperature is 280 degrees - 290 degrees from the CPU's 8 cm is the height of his master, such as: 3508 CPU, removal lon-izing inclined to blow the CPU edges as far as possible the hot wind blows into the CPU below that can easily be intact under the blow of the CPU! How do you go to the CPU is that the same?
(3) mainboard disconnect and drop is mostly caused by improper operation, do you know why? I tell you, especially with glue under the CPU is the most easy to improper operation caused the mainboard break line and a bit, my own experience with glue under the CPU is introduced, the temperature of the heat gun transferred to the scale of heat gun air volume is set to 6.5-5.5 7 actual temperature is 270 degrees - 280 degrees straight on straight down to the CPU to blow everyone know CPU after the general heat sealing glue of soft, such as: 998 samsung to fly after the heat of Po soft sealing glue the glue around the first turn on the CPU heat in to the CPU after clean, heated the CPU wants even let the CPU below the tin all melts in the CPU so as not to appear offline and a bit, do you want to bring in sealing tape on the motherboard or CPU, you can do with a flat screwdriver yourself, is for my own use tin plate of steel plate material, cut 2 cm wide in the image edge grinding can place it with special tools, Melted when you put the CPU below the tin you plug you make your own tools under the CPU you want to the sealing tape on the CPU you plug tool along the main board, if you want to put the sealing tape to the motherboard that you put the tool down the CPU is inserted below is ok, do you know why break line and a bit, because you are in the heating is not heated together most of the CPU below the tin melting caused by a small number of tin also not completely melt, Everyone noticed why the broken line and drop point are in a small piece of the motherboard more other motherboard large are not broken line and drop point ah this is you do not use the air gun on the CPU heating uniform cause! Ha ha know why!
(four) to solder or plastic line sit or keyboard sit and some of the bells and to the power amplifier as the main control of the hot air gun heat and air volume can be! Try it yourself!
(5) blow to weld the CPU is often there will be a short circuit in the new CPU or other BGA IC why sometimes there will be a short circuit phenomenon, my own experience in welding blowing when the CPU or other BGA IC is mainly the motherboard BGA IC position, the motherboard cleaning net flux on besmear below IC IC as the most important is to pay attention to clean in the location of the mother board must be accurate, In IC that blow the CPU or other BGA welding position are not allowed to blow the tin IC will automatically locate you also don't know whether I misplaced so you must pay attention to the IC in the location of the main board to the use of smaller heat gun airflow temperature in 270-280 degrees have to decide, in blow welding system of IC is you to note you tin tin ball is big or small, tin ball big blow in welding is to notice to IC range a little bit small so that it is not easy to IC this tin ball rolled together the cause short circuit, IC solder ball small range bigger can also, I don't know you pay attention to this!
(6) do you know why you pick up the mainboard break or a bit when the CPU of welding between the success rate is so low, I think you didn't find the reason, I will find out the reason of for you, as you all know the M series is 8 CPU break below 998808 and a bit more is a big problem in maintenance, everyone in my own experience introduction, connection I think everyone have no problem but you know what? The key is not on the wiring is on welding, connect you well success rate of bad welding bottom, some in wiring is often use some glue, such as: Green oil, hot glue, 101502 glue to fix his fixed is also a good way to use these glue, but so that your technology is also here so far did not improve the idea of the ha ha see I don't know of a recruit people use it, without glue fixed wiring the following welding good CPU, no matter how much we off line and off point even outside fly line can also once done, Why your attention to this point on the 8088 CPU mainboard position bolt and short point below the CPU of welding between the success rate is higher why 998 CPU mainboard position bolt and short point below the CPU of welding between the success rate is low I think you must know, because 8088 motherboard have apparent CPU white line position of the box so easy but 998 is not easy because it has no CPU position mark of ah, how can be done to achieve welding best position, You know the general position of the blow welding CPU, you should know that the CPU below is a connected line and the spot of the welding, slightly move the line you connected out of it, so the position is the main!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! At most, I connected 7 points of 34 wires, which took 2 hours to fix without glue. Let me tell you about my experience. If you drop points, dig them out first to fill them with tin paste
