      How to improve Auto insertion machine spare parts lifetime ?

      Continuity Tube Life Expectancy

      Applies to tubes used in Generation 8 clinch units.

      The expected life span of a Continuity Tube is dependent upon a number of factors including:

      • Lead Composition

      A Continuity Tube that is subjected to steel leaded components will cause more stress between the cutter, the cutter Bushing, and the continuity Tube. Expect to experience a higher wear rate on a continuity tube that is subjected to stiffer lead material than a continuity tube that is subjected to softer leaded material.

      • Lead Diameter

      A larger lead diameter will cause more stress between the cutter, the cutter bushing, and the continuity tube. Larger leads being cut will accelerate the wear of a Continuity Tube.

      • Tooling Maintenance

      Worn Tooling (cutters and cutter bushings) will cause the scrap lead to ‘tear’ instead of cut with a sharp clean cut. This ‘tear’ in the lead will accelerate continuity tube on both the metal tube and the plastic surrounding the metal tube. The tooling should be changed at recommended intervals, sooner if tearing of leads is noticed.

      • Working Environment (dust, humidity, temperature, etc.)

      The continuity tube should be kept as clean as possible. Dust buildup caused as a result of the cut/form process and clinching process will grind into the metal tube and the plastic surrounding the metal tube possibly causing accelerated wear of the continuity tube.

      There are too many variables associated with the performance of a continuity tube to allow Universal to list it as ‘consumable tooling’ and publish an estimated life span. The greatest life span will be generated by keeping the continuity tube as clean as possible, keeping the lead length within the middle of acceptable lead length range, and changing the cutters and cutter bushings on a regular basis.

      Continuity Tubes and False Insertion Errors

      Proper continuity lead sense is dependent upon the relationship between:

      • the continuity tube
      • the cutter
      • the angle of the lead being cut
      • the lead length as the leads are cut.

      It is important the lead is bent and touches the continuity tube before the cut takes place, making the position where the lead enters the cut and clinch assembly very important.

      As the cutter moves across to the cut position, the lead begins to bend in the direction of the continuity tube.  However, once the lead is pinched between the cutter and the cutter bushing, the scrap portion of the lead will no longer be pushed toward the continuity tube.  At this point the scrap portion of the lead will actually be forced in the opposite direction of the continuity tube as the cutter shears through the lead.

      The following scenario describes what happens if the lead length is set too short.  In other words, the lead entrance to the cutter bushing set so the lead is very close the cutter bushing shear point.

      By setting the lead length too short, (the lead too close to the cut point of the cutter bushing), the scrap portion of the lead will not be bent far enough to reach the continuity tube as the cutter bends the lead, resulting in a false insertion error.  In other words, if the lead reaches the cut point before it has been bent far enough to touch the continuity tube, a false continuity error may occur.

      On the other hand, having the lead length too long may cause accelerated wear and damage to the continuity tubes.  Forcing the lead into the continuity tube with too much force will cause denting of the continuity tube and wear of the plastic insulation, resulting in premature failure and false continuity errors over time. 

      Cutter Stroke Speed and false Continuity Errors

      The length of time necessary to drive the Cutter from the home position, to the extended ‘cut’ position, can affect continuity sensing.  If the cutter speed is set too slow, the cutter air pressure is insufficient, or a mechanical assembly used in the operation of the cutter stroke binds, the cutter will not reach the component lead in the ‘window’ of time necessary for continuity to be sensed.  This will result in a false continuity error.  Examples of cutter stroke speed problems:

      • Pneumatic flow control for the cutters not properly set
      • Poor air flow from the valve to the cutter
      • Binding in the mechanical linkage from the cutter piston to the cutter
      • Lack of sufficient lubrication in the mechanical linkage from the cutter piston to the cutter
      • Incorrectly set cutter backstroke (the starting position for the cutter)
      • A torn O-ring on the cutter piston which causes a bind in the cylinder
      • Lack of sufficient lubrication on the O-ring for the cutter piston

      Avoiding Design Mistakes with Testing

      Improve EMS Productivity by Testing Early

      http://www.smthelp.com/product/high-speed-in-line-circuit-board-test-machine/

      PC Board errors are a drain to EMS productivity. Through analysis and testing PCBs in the pilot stages, a smoother and more educated production set-up can be achieved. By performing automatic impedance measurements and testing of components (chip resistors and capacitors) early on, you can ensure the best design for production.

      We recommend applying the best design logics when creating your PCB layout and Test, Test, Test for maximum efficiency and output. According to Circuits Assembly’s December 2016 Magazine, here is the list of 5 Most Common PCB Design Mistakes: “1. The components do not suit the production technology 2. Thermal imbalance 3. Incompatibility between fabrication and assembly technology 4. Component placement at PCB edge 5. Placing fiducials on the PCB’s edge.”

      Once you have planned your PC Board with best practices, Southern Machinery’s High-Speed In-line Circuit Board Test Machine will help with testing by incorporating a visual inspection function which allows mounting status checks on each component (e.g.: typo descriptions in alphanumeric characters, orientation, size) on the operator’s monitor will serve to best analyze testing up close. As well as automatically generating test data from mounting data and component list.

      How to analyze common failure case of reflow soldering

                    A common fault handling of reflow soldering is analysed


      Reflow soldering heat alarm prompt temperature difference is too big or too small, in the process of computer tip ‘communication failure can’t start the machine, according to the two kind of phenomena, we had a lot of test and analysis work, draw the following conclusions:

      1, in the process of reflow soldering heat suddenly alarm prompt “temperature range of a certain temperature too low or a certain temperature and set temperature difference is too large”.
      Aiming at this phenomenon, we can preliminary judgment fault will occur in the heating or part overheating protection, and so will all overheat protection switch sub let its failure, and start the machine, found that seems to be normal.After further analysis, under the condition of the overheating protection switch sub machine can work, but in the event of heating, the temperature rise too high a less protection of defense, will bring more serious consequences.In order to solve this problem, we must put 16 from heating unit to find out one or several thermal protection switch failure, we will each heating unit with this problem apart, examine its overheating protection switch, found problems the second heating unit overheating protection switch, with a moving contact bimetallic strip fixed weak, cause the moving contact and the static contact point contact is not good, or not at all contact (normally two contacts should be contact together and conduction).Because there is no the second heating unit of the spare parts to replace we will switch sub to ensure production run smoothly.To this can solve the problem, but as soon as possible to the broken overheating protection switch is off, so as to achieve the purpose of protecting the second heating unit.

      2, if the downtime is longer, when it turns switched on again reflow computer tip ‘communication failure and can’t start the machine for a long time to let the heat.
      Aiming at this phenomenon, we preliminary suspect as the communication line fault, then replaced the telecommunication lines, the question remains, so denied this conjecture.After further observed, when the communication is not successful, the lights on the status of the controller is not normal, orange lights should be flashing, and should not go out.Based on manual measuring line 1001 and line voltage between 1007 found that the voltage is not constant for the + 5 VDC, about + 2 VDC when communication is not successful, the problem is out of here, why the voltage is too low, the original control panel in the end of the machine here are two simulated load resistance, resistance ought to be ‘5’R , but actual value only two ‘2’R, but I have measured the value to change it into ‘5’ R problem is resolved.
