MITS Prototyping Printed Board Maker

MITS Electronics is the only manufacturer of prototyping printed board making equipment using milling technology in Japan. In business since 1983, there are now more than about 3,000 MITS prototyping printed board systems in use worldwide.

Since the MITS prototyping printed board system allows users to create a PC board close to the finished product within a day, it effectively shortens development times, cuts costs, and streamlines the overall development process.

Board Making Process

The milling process is employed to produce a shallow channel around the pattern on a plain copper-plated PC board. By leaving the pattern as an island, MITS board makers are able to mill boards with multiple ground surfaces.

When the surface pattern is completed, the holes are drilled and the external shape is produced. Finally, the rubout process can be used to remove unwanted copper plating if desired to produce a board just like the etched board.

Basic Board Making Steps

1. Drilling
First, place a board at the center of the under-plate and secure it with tape on all four sides. Then, set the milling reference point(s) (P1 and, if needed, P2*). Next, drill the reference holes at these points. Now, the other holes can be drilled using drill bits of the required diameters.

* P2 is used for double-sided PC boards. P2 is the reference point used when the board is turned over for milling the other side.

2. Milling the pattern
The milling process produces a shallow channel around the outside of the pattern, leaving it as an island. Boards of multiple ground surfaces can be drilled.

3. Rubout
In the rubout process, unwanted copper plating is trimmed off to produce a board that looks just like a regular etched board.

Software

MITS offers a module that converts circuit pattern data created on a host PCB CAD system (and output in Gerber format). This module then automatically generates the paths (outline) along which the board maker's tools will move.

Patterns can also be created using MITS own EASY CAD software. EASY CAD runs on a Windows 95/98/2000/NT/XP platform.

Variety of Models of Prototypying Printed Board Makers

MITS offers variety of models to choose from. At the affordable end of the line is the FP-7A, and at the high end is the high-speed, high-precision DFM-400 with automatic tool change, built-in CCD camera, and 2D auto-measuring functions.
