SMT parts are widely used in various fields of electronics, SMT parts products have a compact structure, small size, vibration resistance, production efficiency and high advantages. One of the final equipment is the punch machine. So do you know how engineers in the punch machine SMT programme into the itinerary design?
SMT engineer is mainly responsible for SMT machine maintenance, repair, SMT engineer is a higher level of SMT processing field of a technology level positions, the need to be able to patch the basic debugging machine, programme design, repair, maintenance and so on.
In the SMT punch machine on the optimisation of the product program editing
1.Call out the optimised program.
2,.Do PCB MarK and local Mak Image image.
3.Image the components that have not been imaged and register them in the image library.
4.Register the unregistered components in the component library.
5.To discharge unreasonable multi-tube vibration feeder, according to the length of the device body for re-allocation, as far as possible to the body length of the device is closer to the device arranged in the same material rack: and will be placed in the material station to hold a little tighter, as far as possible in the middle of the idle material station, so as to shorten the pick-up components of the journey.
6.The program in the larger size of the shape of the multi-pin, narrow-pitch devices, such as 160 pins above the QFP, large-size PLCC, BGA, as well as long sockets, etc. to Single Pickup Single Pickup pipeline, which can improve the accuracy of the mounting.
7.Save the file to check whether there is error information, according to the error information to modify the programme, until there is no error information after saving.
SMT Programming
Proofreading, checking and backing up the SMT punching programme.
1.According to the component list in the PCBA process file, check whether the component name,bit number and model specification are correct in each step of the programme,and correct the incorrect parts according to the process file.
2.Check whether the components on each feeder station of the laminator are consistent with the pick-up table.
3.Use the main monitor to check whether the X and Y coordinates of the components in each step of the laminator are the same as the centres of the components on the PCB, and check whether the corners are correct according to the component position diagrams in the process file, and correct any inaccuracies. (If this step is not carried out, it can be corrected according to the actual mounting deviation after the first SMT mounting.)
4.Copy the correct product programme to the backup USB memory stick and save it.
5.Proofread and check the correctness before production.
Online debugging SMT punch machine
1.Import the programme into the SMT machine by computer,find the origin and make the mark mark.
2.Correct the coordinates step by step,optimise and save the program,and check the direction and data of the components again.
3.Start the machine to play a piece of the first board to confirm.
