SMT SEMI cleaning machines for leadframe with QFN for semicon
SMT SEMI cleaning machines Features :
1)This system is constructed by SUS304 stainless steel material, It is an intergrated machine with very good acid and alkali resistance.
2)Flat net conveyor and special net transport mechanism, make it very stable.
3)Long wash section, prewash+wash1+wash2, perfect flux cleaning effect, more easier to set machine parameters.
4) Long rise section, pre-rinse+rinse+final risne,meet the requirement of cleaness. Powerful and high flow air blower, special design air knives, super air blow effect. 5)Long heat dry section and SUS316 air heater,special air knives, make it perfect air heat effect.
6)Several type of high volume spray nozzles, cover both high immerse and spray pressure requirements.
7) Equipped with low noise high performance air blower, to reduce noises and improve environment.
8) Equipped with liquid level sensor to protect the system working on normal water level and prevent water level abnormal to protect heaters and pumps.
9) Water tank bottom tilted design, so that water can drain off, for the convenience of water tanks maintenance.
10) Equipped with water flow meter for the operator to know water consumption.
11) Wash and rinse sections 3 layers seal: no liquid mist or water vapor leakout.
12) DIwater overflow replacement: DI water overflow replacement from final rinse to rinse section , rinse section to prerinse section.
13) Double liquid or water LS protection: Double LS in each liquid or water, double protection.
14) Double tempreture detector protection: Double tempreture detetors in each liquid tank ,water tank, hot air section, double protection.
15) DI water resistance real time monitoring: inlet DI water quality check.
16) Two sets of spray pressure and air meters
SC820 electric control safety protection
1) Mitsubishi PLC ,and touch panel operation interface, easy for operator to use this system
2) 3-color indicator and alarm buzzer design to ensure the operator to know system running state; If there is any abnormal situation happens,the buzzer will give out noises and red light will twinkle.
3) There is a light sensors on the entrance section of the system. If no chips are put in over setting time, the system will turn off pumps and air blowers to save energy and water. The system will awake when new chips are put in again.
4) Equipped with chips drop alarm function, monitoring chips in time.
5) Heat temperature adopt automatic PID and analog quantity control calculation system to firmly control temperature deviation,make temperature rise more stable.
6) Equipped with auto temperature control system and over temperature protection function to avoid damage to the system.
7) All pumps,air blowers,heaters are overload protected to avoid damage to them.
8)Current surge protection: all electric devices start every 2 seconds one by one to reduce instant current shock.
9) Power failure protection: Equipped with UPS system for net conveyor to send out 3D glasses trays at the time of sudden power failure.
10) Alarm when the system is in trouble, trouble information will be shown on touch panel for the convenience of trouble shooting.
