Repair of equipment requiring the use of lead-free soldering
Transition to lead-free solders quite expensive. This is due to the need to use more expensive soldering equipment and consumables, and with the need to upgrade the skills of workers, to develop new technologies. The process involves the use of higher temperatures, the upper limit up 30-40 degrees as compared with using tin-lead solders, so the work required to comply with more control. Whatever electronic components are not out of order during soldering, you must strictly adhere to the time parameters, and the temperature is strictly controlled at the hardware level.
used today contact and non-contact soldering stations. The simplest may be considered Thermoair, but in terms of process control is not good enough, therefore increasingly found infrared soldering stations. Using an infrared heating also makes it possible to uniformly heat the maximum chip BGA, at the same time all the conclusions oplavit, even more serious claim for repair, than the production.
Equipment for lead-free soldering
As noted, There contactless and contact soldering methods without tin-lead solder. Regarding a first method, and apply Thermoair infrared furnace and soldering stations. For the production of the question is more price, as finished products should have the most competitive price. Both options can provide the right equipment. For local soldering of single instances, and repair more pressing question of the quality of work. And then come to the fore is infrared models, поскольку они могут разогревать BGA плату локально, only there, where it is required to carry out replacement, installation or removal of the element.
A good example is Infrared Soldering Station ACHI IR6500. Its main advantage is the ability to work with CBGA, CCGA, CSP, QFN, MLF, PGA and all types of epoxy boards μBGA.
market contact soldering equipment for lead-free soldering significantly less. Basically, This Soldering-Tweezers with two stings for dismantling, as a model ZD-409. But they only use voiced in the title. High soldering capable often are done locally soldering, complete with infrared harvesters and find a station separate from the installation is difficult to.
