Material of squeegee is stainless steel ; Rigidity of squeegee is ≧100° ; Angle of squeegee is 60 ° .5、Attention： 5.1 By mode to load program and stencil,The following parameters will be entered after loading an old program or making a new program. 5.2 After change the model , the operator is responsible for adjusting the tooling pin position by the tooling pin position by the tooling pin pattern, then the foreman have to check it with SMT checklist. Setting tooling pin refer the procedure as below: Step operation until PCB loading to M/C ,and table lift , then loose the snugger, replace with the tooling pin pattern , then operator can adjust with the pattern 5.3 Use stencil must check direction,the arrow should be left to right and Pcb direction must same as stencil. 5.4 Only M.E. and Test OK Of Person can be adjusted by line operators with the limits above ,but if the parameters mightbe adjusted over the limits by some reasons, inform the supervisor . The adjusted parameters should be recorded in the daily downtime report,and tell the next shift . Do not adjust the other parameters. 5.5 Before using the stencil, you should check the version and if the stencil is clean . Before and after using he stencil, use the stencil washer(SAWA) to clean it and manually remove the solder powder on the stencil；after cleaning ,return the stencil to warehouse. 5.6 After setting up the stencil , and start to print the 1st PCB, need to press F1 , and in the end of print stroke, press F6 knead paste. Do the same procedure 3 times. (Amount strokes are 4 times) 5.7 After printing , the 2nd and 3rd (one for front , another for rear squeegee) have to be taken to measure the solderpaste thickness,refer the smt solder paste thickness spec. If the result is within the control limit , then inform the line to continue printing. 5.8 After production , please take off the squeegee and clean it . Then please turn back the squeegee to stencil warehouse. 5.9 Before open and use the solder paste , have to mix the solder paste by mixing machine , and the time setup is 18sec( 0.3 min). 5.10 When adding solder paste , please add half of the stirring knife solder paste in stencil every time.Before printing, please add solder paste seven times; During printing, please add twice solder paste every80Pcs.If there are solder paste in the edge of stencil ,please use stirring knife to move them to the center of stencil. 5.11 Whenever you open the cover for some reasons, be sure to close it immediately after the work is done. 5.12 When the machine stop over 1hour for some cause, solder paste in stencil and squeegee should be taken back into tin, then clean stencil and squeegee manually; If there are solder paste in stencil surface and hole wall , please use solvent to clean them(Reference: C-5-1-1-QW0933). If the printed PCB don't be mounted components over 1 hour, the solder paste in PCB should be clean by machine 5.13 The clean paper can be used by only one time. 5.14The solvent for cleaning the stencil is YC-336A ，do not use the wrong solvent. 5.15 Solder Paste Brand Is KESTER , Solder Paste TYPE Is R253-5 10% , ALLOY: SN 63/37 MESH:-325+500 5.16 Need more detail on printer operation, refer to “C-5-5-2-QW0934”. 5.17 Need more detail on solder paste control, refer to “C-5-5-2-QW0904” & ”C-5-1-1QW0905” & ”C-5-1-1-QW0959”. “SMT DEK CONTROL LOG (C-5-1-1-QW0916-06)”,\"Operation of Cleaner Control (C-5-1-1QW0933) 5.18 To clean steel board once every 12 hours when continue product,do well in and out' record of steel board and record of steel board washing. 5.19 Operation circumstance control according to <
>(C-5-5-2-QW0938). 5.20 After print 80 pcs PCB board, must clean stercil one time by manual. 5.21 Make sure the board stopper is contacting with the Golden Finger, instead of any other part of the board.APPROVED BY :ISSUED BY: APISSUE DATE:DOC VER: 1.0
