AND CHARGES, AND THE CASE

Familiar to many hams, the situation: once the scheme is built, configured, but… to Squeeze it into some kind of “soap” not want to, but new to “diamond” the right frame there is neither time, nor forces. Had to find a way out of similar situations and me while in one of the publications, “Model construction” did not find a clue. It turns out that enterprising and slopestyle Siberians, which wrote the log, began the production of fine gift boxes of foil materials commonly used in the manufacture of printed circuit boards. Moreover, the simplest technology: the workpiece-scan in the field of future folds (from the base-insulator), they made cuts, and after giving it a box shape was probabaly foil joints.

 

In the formulation of this problem soon followed. I hope it will be acceptable for other Amateur designers. Vedas s hull produced by the proposed method, get good-quality. Strength, elegance, moisture and heat resistance inherent in the base material of the insulator (and the PCB, phenolic paper or glass fiber), ideally complemented by the valuable properties of the conductive layer (foil), including the ability to serve as an electrostatic screen. In addition, the manufacture of such a case takes only an hour and a half (about 70 percent of the time is spent on propeica seams).

The proposed technology complexity is no different. And in order to be able to understand and apply even the student doing first Amateur design, it is presented in the form of icons.

 

The manufacture of the body starts with the fact that the sheet of foil material (having, for example, stegotexts-tovuu basis) cut the workpiece bottom, lid, sides, front and back panels. Their sizes depend on the dimensions created by Amateur design. If you need housing width x, length y and height g, and the thickness of the source material (the layer of foil) — s, then the workpiece should be such that what is depicted in “zero” illustration (POS.O). The General idea, they carry out the holes for the terminals, buttons, electrical appliances, etc.

 

 

Icons that reveal the technology of making the body of the foil material of printed circuit boards.

 

Then foil the edges of the workpieces deserve. On the front panel, located on the base-insulator down, put alternately the sides and soldered to it at a right angle. Turning scalabrino the resulting design 180°, solder rear panel (POS. 1).

 

From foil fiberglass cut out four triangular joint. Each drilled holes with a diameter of 5 mm, flat needle files chiseled them to the hexagons — seats for nuts M3, which immediately presoviet in a Vice or pliers (POS. 2-5).

Serial installation (POS. 6), the resulting itica elements securing the cover in its place lead to an increase in stiffness.

 

Attaching the lid to the box is almost ready, from the pressed nuts make marking holes for M3 screws (POS. 7). Drilling also perform, while holding the cover in a vise.

 

The last stage of solder — mounting of the bottom to its place (POS. 8). Almost completed housing is placed an electronic “stuffing” and fix the cover with screw (POS. 9). And, as they say, though.
