Anyone, even a well-equipped modern machine shop to do probably without soldering. And no matter how they fought for the engineering is still in front of us (according to the definition of “Explanatory dictionary of the live great Russian language” V. Dahl) — “iron of different types, in a wooden clasp which is kindled, and, holding it across the metal and tin solder first.”
However, the wooden clasp is now increasingly replacing the plastic handle with additional devices. Go to other tricks, with the result that the scope of application of the soldering iron a few extends. The description of such technical solutions with sketches of the corresponding structures is possible, in particular, on the pages of the journal “modelist-Konstruktor” (see for example, № 5’66, 7’68, 12’75, 3’79, 1’82, 2’83, 3’91, 6’91, 7’94: 3’97). Two original, from the point of view of the editorial Board, the soldering, the authors of which are our readers A. NAUMOV of the Samara region Vladimir YASHIN from Tatarstan, dedicated to the following factsheet.
We offer the option of homemade microbalance with a built-in device for removing solder when dismantling is addressed primarily to radio Amateurs and those who have to deal with the installation and removal of chips and low power semiconductor devices.
The basis of the fixture is… medical syringe with needle which (after slight modification) and is a working body (Fig.1). The power consumption of the heating element (again, homemade!), does not exceed 12 watts. But it is enough to bring the temperature of the soldering tip to 300°C.
The old needle (beveled) the end removed by the cutters, the edges of the cropped part is slightly turned to the emery bar. Landing on the other end cut with an annular groove for the locking washer is used to fasten the housing of the mini-socket (Fig.2A). The thus obtained stinger microbalance inserted into the copper tube-the base of the heating element. The technology of its making is presented in figure 2 and differs little from that described 6 No. 3 of the journal “modelist-Konstruktor” for 1997. We only note particular.
