Generally in the circuit overhaul, often from the PCB board assembly integrated circuit, due to the integrated circuit pin and intensive, assembly is difficult, and sometimes damage IC and PCB board. Here summarized several effective integrated circuit assembly method, for everybody reference.
Multi stranded copper wire suction tin assembly method: is the application of multi shares copper core plastic line, remove the plastic skin, the use of multi stranded copper wire (can be used for short-term head). Before the use of the first multi strand copper core wire on the rosin alcohol solution, until the heat of the electric iron will be stranded copper core wire into the heat on the chip pin. This pin soldering will be copper adsorption, the ceiling on the solder local cut to, repeated several times can be sucked all pins on the solder. There is also the use of shielded wire within the braided line. Just put the soldering tweezers smoked, or small "one" word screwdriver gently pry, integrated block can be taken by the.
Growth solder ablation assembly method: the approach is a convenient way, just to to be assembled chip pin on the re growth of a little tin, solder joints in each column pin link up, so in order to facilitate heat transfer, ease of assembly. Assembly with electric iron per heating a row of pins with forceps tip or small "one" word screwdriver pry lever, two rows of pin rotation heating, until removed so far. Under normal circumstances, each column pin two heating can remove.
Electric iron with brush assembly method: this method is easy and convenient, only need to have an electric iron and a small brush can. Assembly integrated block when the electric iron heating, until arriving at the dissolved tin temperature will pin solder ablation, took the opportunity to brush sweep melted out of the solder. This can make the integrated block pin and the PCB departure. The approach can be implemented by the foot can also be disaggregated. The final tip tweezers or small "one" word screwdriver under the integrated block.
Medical hollow needle assembly method: take medical 8 to 12 number of hollow needle. The use of needle in the right over the chip pin is appropriate. Assembly with iron will pin solder melting, timely put a needle trap pin, then take off the iron and rotate the needle, after the condensation of the solder pull out the needle. This pin is separated from the printed board. After all pins do so, the integrated block can be removed optionally.
Ceiling Tin Tin sucking assembly method: using the ceiling assembly tin integrated block. This is often used as a professional way, using tools for common suction and welding dual-purpose electric iron, power in the 35W above. Assembly integrated block, just after heating dual-purpose electric iron head on to be assembled chip pin, to be solder after ablation is inhaled fine tin, solder pin all the ceiling after integrated block can be removed.
