Generally in electronics industry, solenoid bulb is not categorized in inkjet technology, however, in bio industry, most of the cases, inkjet means solenoid system. We have to point out that the principal and performance is totally different in these two. Although piezo inkjet has great technical advantages, it was not accepted in Bio industry. This is due to the fact that piezo inkjet cannot stably eject aqueous liquid which has high surface tension. But, finally Microjet have overcome this obstacles. Now that piezo inkjet can handle aqueous liquid, it's technical advantage is getting people's attentions.

The followings are advantages of piezo inkjet technology

• Handling liquid droplet volume is quite small
• High speed
• No direct contact to substrate
• No scattering on substrate

Piezo Inkjet vs Solenoid bulb

Type	Piezo	Solenoid bulb
Minimum droplet size	1 Pico litter	10 nano litter
Droplet generate # (sec.)	2,000 - 50,000 pcs	500 pcs
Accuracy	within ±1%	±5 - 10 %
Life/durability	10 bil.	0.1 bil.
Liquid Viscosity (max)	500 cps	50cps
Liquid supply system	no need	pressure pump

Obviously, piezo inkjet has overwhelming superiority, however, it requires know-how's to fully control this technology.
