An Analysis of SMT Solder Paste Printing Defects

An Analysis of SMT Solder Paste Printing Defects

In SMT PCB production, solder paste printing is a critical step. Since the solder paste is used to directly form the soldering joint, the quality of solder paste printing affects the performance and reliability of the surface mount assembly. Quality solder paste printing guarantees a quality solder joint and final product. Statistics demonstrate that 60% to 90% of soldering defects are related to solder paste printing defects. So it is very important to understand what causes defects in solder paste printing.
ItemFactorsAnalysis1Solder PastePowder formationThe irregular shape of solder powder will easily clog stencil apertures. This will cause a big slump after printing. It can also cause solder ball and short bridge defects after reflow.

A spherical shape is best, especially for fine-pitch QFP printing.Particle SizeIf the particle size is too small, the results will be poor paste adhesion. It will have a high oxygen content and cause a solder ball after reflow.

The particle size should be controlled to about 25 ~ 45 μm in order to meet the requirements for fine-pitch QFP soldering, If the partical size desired is 25 to 30 μm, it should applied with less than 20 μm solder paste for an ultra fine-pitch IC.FluxFlux contains a thixotropic agent, which allows the solder paste to have pseudoplastic flow characteristics. Since the viscosity decreases when the paste passes through the stencil apertures, the paste can be applied to the PCB pads rapidly. When the external force stops, the viscosity will recover to ensure no deformation occurs.

The flux in the solder paste should be controlled to between 8 and 15 percent. A lower flux content will result in excess amount of solder paste applied. Conversely, a high flux content will result in an insufficient amount of solder applied.2StencilThicknessA stencil that is too thick will cause a solder bridge short.

A stencil that is too thin will cause an insufficient solder to be applied.Aperture sizeWhen the stencil aperature size is too big, a solder bridge short can occur.

When the stencil aperature size is too small, and insufficient solder paste will be applied.Aperture shapeIt is best to use a circular-shaped stencil aperture design. Its size should be slightly smaller than the PCB pad size, preventing a bridging defect during reflow.3Printing parametersBlade Angle Speed & PressureThe blade angle affects the vertical force applied on the solder paste. If the angle is too small, the solder paste will not be squeezed into the stencil apertures. The best blade angle should be set around 45 to 60 degrees.

A higher the printing speed means that less time will be spent in applying the solder paste through the stencil aperture surface. A higher printing speed will cause insufficient solder to be applied.

The speed should be controlled to around 20 ~ 40 mm/s.

When the blade pressure is too small, it will prevent the solder paste from being cleanly applied to the stencil.

When the blade pressure is too high, it will result in more paste leakage. The blade pressure is typically set at about 5N ~ 15N / 25mm.4Printing process controlPCB moistureIf the PCB moisture is too high, the water under the solder paste will quickly evaporate, causing the solder to splash and creating solder balls.

Dry the PCB if it was fabricated over 6 months ago. The recommended drying temperature is 125 degrees for 4 hours.Paste storageIf the solder paste is applied without a temperature recovery period, the water vapour in the surrounding environment will condense and penetrate the solder paste; this will cause the solder to splash.

Solder paste should be stored in a refrigerator at 0 to 5 degrees.Two to fours hours before use, place the paste in a normal temperature environment.

                                    How to maintain Auto Insertion and SMT machine — ESD Cleaning and Testing Procedures

                                    Procedures and Adjustments

                                    CAUTION

                                    The following procedures explain how to properly clean and test an ESD surface.

                                    Clean an ESD Surface

                                    Do not use abrasive or highly alkaline cleaners on polycarbonate. Never scrape polycarbonate with squeegees, razor blades, or other sharp instruments. Benzene, gasoline, acetone, or carbon tetra chloride should never be used on polycarbonate. Do not clean polycarbonate in the hot sun or at elevated temperatures.

                                    1. Using a sponge or soft cloth, wash the ESD-protected surface with either a mild detergent or Windex product and lukewarm water.
                                    2. After washing, rinse with water and dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.
                                    3. To protect the ESD surface after rinsing and drying,  recommends applying Kleenmaster Brillianize®. This application helps to maintain the static dissipative coating and reduce the accumulation of dust.

                                    Test Static Dissipative Covers

                                    Periodically and after maintenance, check the machine covers to determine if the dissipative qualities of the cover have changed. The following procedure ensures that static dissipative covers are in fact dissipative.

                                    Tooling

                                    Surface resistance meter (such as 3M 701 Surface Resistance meter and probe).

                                    Comments

                                    The surface resistance should be less than 109 ohms in all areas. If the cover package is no longer dissipative, contact you Universal Instruments Corporation sales representative.

                                    Procedure

                                    1. Clean the static dissipative covers using the Clean ESD Surface procedure to ensure the accuracy of the test.
                                    2. Using the surface resistance meter, follow the instructions provided by the manufacturer to measure the surface resistance of both the inside and outside of the covers. Measure the resistance at all four corners and at several areas in the middle of the cover. This test checks the integrity of the ESD coating.
                                    3. Connect the ground path resistance probe to the meter and chassis ground.

                                    The path to the ground should not be higher than the surface resistance. If it is, clean the frame connections, repair loose or corroded fasteners and ground straps, and check tracks for dirt and/or corrosion.

                                    4. Measure the ground path from the covers to the chassis ground. Take this measurement from both surfaces and all four corners of each cover.

                                    THT Thriving in the Pro-Audio Industry

                                    NAMM Show 2017

                                    NAMM THT Music Industry Odd-form automation machines PCB Boards

                                    While in attendance at the 2017 National Association of Music Merchants (NAMM) Show last month we found one thing to be true… THT Equipment is far from dead. The music industry continues to require robust and durable components for high quality and heavy duty gear. GEAR, GEAR, GEAR! And the better the gear the more likely THT was involved in the assembly. Proving that THT is not just surviving but thriving in our high-tech world.

                                    But there are many missing links! Many of these specialty components are still placed by hand and many more are still IMPORTED. Opportunities abound for manufacturers to bring all assembly, quality control, and profits back home. Quality is the name of the game when it comes to being #1 in any product category but costs sometimes hold back some manufacturers. According to Joel Menchey, Menchey Music Service, import costs for audio manufacturers are the highest of all costs. This doesn’t have to be so.

                                    We at Southern Machinery have the solutions to lower costs and improve your manufacturing assembly quality! Our S-600-OF Through-hole & Surface Mounting Multifunction Machine paves the way to incorporate THT with SMT technologies. We can help you design the exact machine for your needs, ordered to spec. It’s a simple conversation for a huge shift in ideology and savings.

                                    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.

                                    Stop Importing Cell Phones, Automate Them!

                                    Times have officially changed. Where once there was no reason to invest in your homegrown cell phone manufacturing, now, with equipment that is more affordable than ever before, it makes sense to invest at home. Cell phone suppliers don’t have to rely on other countries to import cell phones any longer with new Smart Factories that are more efficient and affordable than labored hands.  Now, businesses can incorporate manufacturing into their business model, and finally stop importing from China.
                                    The SMT, pick and place Industry has revolutionized the way we used to look at manufacturing. The reasons for importing cell phones from China, namely cost and labor, are being reduced with the advancement of PCB AI Assembly equipment. Now you can home-grow your cell phone manufacturing with equipment that is smarter, faster, efficient, and more affordable than human labor force.

                                    These huge changes will affect all companies that rely on electronics manufactured abroad. These imported items that have been historically low in cost, will no longer have the same low price tag. Intelligent companies are staying ahead of the curve and beginning to create their own reliable manufacturing processes, IN-HOUSE.

                                    The good news is that there are companies that have planned ahead. It is now easier than ever to begin or improve your own manufacturing capabilities. It is not the huge undertaking it once was to establish and expand your own manufacturing equipment. PCB AI Assembly equipment is smarter, faster, efficient, and more affordable than ever before. Now is the time to get on board!
