The pistol is usually directed either normal to the capacitor end or up to 15º from the normal. The sprayed coating thickness is determined by the winding quality and is usually 0.014″-0.016″ (350µm – 400µm) but for some high class thin film capacitors, coatings may be thinner 0.010″-0.012″ (250µm – 300µm).
The choice of coatingdepends on the joining technique; usually the coating is mainly zinc with the final 0.003″- 0.004″. Zinc wires are also used in the capacitor technology and have extremely favorable results.
Electronic encapsulation refers to enclosing electronic components in protective materials to safeguard them from moisture, dust, temperature fluctuations, and mechanical stress.

The ends of the roll are then sprayed with metal to link up the electrodes and provide a surface for attaching the terminals. Larger, specialist capacitors are also sprayed. Many metals may be sprayed on to the ends of capacitors; copper, brass, aluminium, zinc and tin- zinc alloys have been employed.
