PCB solder paste printer for SMT is needed to screen print solder paste onto the printed circuit board (PCB) before placement of surface mount components (SMD) for Reflow Soldering. Automatic PCB solder paste screen printer with pecial
solder paste printing is a critical step in the SMT PCB production, 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,high q

Questions are: * Are you sure there was solder on the pad prior to placing the component? * Is there solder on the lead, but not on the pad?

If it were other machines I would suggest the possibility of air kiss blowing the solder away, but mydata's have a release to make sure the air kiss never gets too high. Unless it is not pointing 90 degrees away from the machine like mydata recommend

By davef: I was fortunate to be able to attend the SMTAI Exhibition Oct. 18-19, 2011. While I was walking around looking at the booths and talking to the exhibitors, I got this idea that I would report back on things that I found interesting. You know spread the news, since not everyone was there.

This year, MIRTEC will launch several new inspection machines equipped new cutting-edge technologies. MIRTEC is proud to be promoting these new machines in booth #1J10 at NEPCON China 2017, one of the biggest technical exhibitions of SMT and EMA, from April 25-27 at the Shanghai World EXPO Exhibition & Convention Center. MIRTEC’s new machines have been developed under a concept, ‘Perfect Inspection Solution’. This is an inspection concept involving the combination of 3D, 2D, and side-camera inspection.

While experienced inspectors may be able to determine the aesthetic differences between a lead-free PCB assembly and a tin-lead version, one cannot rely on the "experienced eye". "Less wetting out to the pad edges" (Figure A) and "graininess and lack of shininess of the solder joint" (Figure B) are typical comments about some lead-free solder joints. However, in cases where a Nitrogen atmosphere was present during the reflow of the solder joint (Figure C), there will be little visual differences between the lead free alloys and their tin-lead counterparts.

Over the last few years, there has been an increase in the rate of Head-in-Pillow component soldering defects which interrupts the merger of the BGA/CSP component solder spheres with the molten solder paste during reflow. The issue has occurred across a broad segment of industries including consumer, telecom and military. There are many reasons for this issue such as warpage issues of the component or board, ball co-planarity issues for BGA/CSP components and non-wetting of the component based on contamination or excessive oxidation of the component coating. The issue has been found to occur not only on lead-free soldered assemblies where the increased soldering temperatures may give rise to increase component/board warpage but also on tin-lead soldered assemblies.
