Description

This is the original FLEXI-BOX (63.5 mm long x 50 mm wide x 25 mm deep) and it is now available with blank photo-resist coated PCB's as well as your custom selected connectors.

[Parts used to make the Transmission Line kit] Typical component parts of a FLEXI-BOX kit.

The basic FLEXI-BOX kit is supplied with two photo-resist PCB's which are ready for exposure and etching. The PCB is already cut to fit the box and has holes ready drilled for installing into the box. The board is therefore ready for exposure and etching. Alternatively, the copper surface may be cut by using a craft knife and the copper lifted with a hot soldering iron. There is an alternate version of PCB available which has a 50 Ohm Transmission Line already etched through the centre and is normally easier to use if the etching process is be omitted. The process for building a prototype in the FLEXI-BOX is illustrated in the Building a HF amplifier in a FLEXI-BOX Part 1.

The box is designed as an enclosure for making prototypes and is extremely easy to work with. The bottom is removable thus making it possible to change through hole components or links without removing the connectors or PCB. It is easy to ground any part of the circuit on the PCB to the box using a conductive tool (the handle of a pair of tweezers is very suitable for this), thus making it easy to find grounding and instability problems. The connectors and PCB can be quickly removed and replaced without damaging them. Connector types can also be changed within minutes and we currently supply BNC(m), BNC(f), N(f), SMA(m) and SMA(f) connectors for this purpose. In fact, once you have built a prototype in a FLEXI-BOX you will probably never want to return to your old methods.
