Manufacturing Nozzles, Charging Plates and Deflection Assemblies into a Prealigned System

In Fig. 1, a plastic nozzle plate 2 has holes 4 bored therein by drilling, by a laser or the like.

In Fig. 2 a charging plate 6 formed of either a metal or a plastic, which may be plated, has holes 8 bored therein in a manner similar to which the holes 4 were bored in the plate 2. After the charging plate is drilled, if a plastic is used, it is metallized on one face and in the interior of the holes 8.

As illustrated in Fig. 3, the nozzle plate 2 and the charging plate 6 are bonded together in alignment and then are diced along the lines 10 and 12.

If a quartz or another insulating material is used for the nozzle plate 2, then the charging plate 6 may be made from metal if mounted in an insulated assembly.

Another method of manufacture of the assembly, is to include the deflection plate and charging plate in a single structure as an extension of the charging plate, as illustrated in Fig. 4. The charging plate 14 is machined such that the deflection plate 16 projects from the charging plate. This structure is then bonded and aligned with the nozzle plate 18.

Fig. 5 is a cross section of Fig. 4, which shows how a metal 20 is deposited on the charging plate 14 to form a film for charging, and a metal 22 is deposited on the deflection section 16 for forming a film for the deflection. After the nozzle plate 18 is bonded to the charging and deflection plates, the assembly may be d...
