Machine Description

SME-800 Water Based Liquid 29*29 Inches Size Mis Printed PCB Cleaning Machine And Stencil Cleaning Machineis an automatically, water base liquid clean and DI water rinse machine. It can clean stencil size up to 29*29mm.

Liquid and water can add and discharge automatically.

SME-800 Multiple application: solder paste stencil, red glue stencil, 3mm thickness red glue cooper stencil, 3mm red glue plastic stencil, mis-printed PCB and squeegees.

SME-800 cleaning process: water-based liquid wash--DI water rinse--hot air blow dry.

SME-800 has the stable mechanism structure--4 cleaning spray rods and 4 air knives fixed at the left and right side of stencil; stencil move back and forth in the cleaning cabinet..

Machine Features:

1. Process: water-based liquid wash + DI water rinse+ hot air blow dry process.
2. Multi-use: solder paste /red glue stencil, red glue cooper stencil/ plastic mask, mis-printed PCB, squeegee.
3. Stable mechanism: stencil moves back and forth in the wash cabinet while spray rods and air knives fixed.-- make the machine stable and relaible.
4. Excellent cleaning result: up to 4~5kg/cm2 spray pressure and high volume nozzles, very good cleaning result.
5. Real time filtrer system: liquid and water can be recirculated used, no solder balls comes back to stencil surface again. Especially for precise stencil.
6. Less distance, more efficient:4 spray rods and air knives fixed on left and right side of stencil, 750mm long stencil move distance reduce to 420mm.
7. Pressure meters : cleaning liquid / rinse water/liquid filter/water filter pressure meters on front panel,easy to watch and monitor them.
8. SUS304 stainless steel structure:alkalic and alkacid corrision protection. All pipes, fIlter barrel and pumps are sus304 material, no plastic pipes at all.

9. One key easy operation: just push “start” key, all process are running automatically according to program setting.
10. Visible: window on right side of clean chamber, all process are visible.
11. Liquid cost down: Compressed air blow out remain liquid in pipes and pumps after cleaning process , save up to 50% liquid.
12. PLC control, TP English operation interface: clean time, temp;rinse time, temp; dry time, temp...parameters easy to set and modify.
13. Auot liquid and water add and discharge function:Equipped with air pump liquid/water add and discharge automatically.
14. World famous, high quality parts from Scheidier, Mitsubish, Omron, SMC, CKD.
15. LS protection: 4 levels liquid and water levle switch, low level to protect heater, pumps,M and H level remind to add liuqid or water,HH level to protect overflow.
16. Heaters temp control: PID calculattion , ±3°accuracy,over temp protection.
17. Water open loose and close loop: both this 2 loops can be choosed to use.
18. Excellent software function: auot/manual mode, I/O ports, paramenters setting,filter replace reminding...

Questions and Answers:

Q1. Why choose this electric stencil cleaning machine?

A1: Because SME-800 use water-based liquid which is safety, environmental-protection and easy to rinse.

Q2: Can SME-800 clean 3mm thick red glue printed cooper stencil and palstic mask?

A2: Yes, it can because its powerful cleaning pressure can penatrate very little holes in the stencil and mask to wash the red glue out.

Q3: Is it very dry after wash, rinse and dry process?

A3: Yes, it is very dry because hot air temperture and air blow result.

Q3: How SME-800 clean mis-printed PCB, squeegees and frameless stencils?

A4: By using our mis-printed PCB fixture, squeegee fixture, frameless stencil fixture.
