Question: I am going to start placing 3mm x 3mm plastic smt leds and want the absolute lowest errors caused by the nozzle either dropping or allowing the part to shift. Would a 2.5mm nozzle be too big for the 3mm part. My logic is that the more surfa

There seems to be less play in the pocket than with other parts i've loaded. I was assuming the large nozzle would work better but for reasons unknown to me it didn't. I also tried a 1mm and had parts all over the machine (can you say hand place 100+

As a market leader in selective soldering and a supplier of innovative hybrid rework systems, Ersa had the courage to adapt its soldering machines to the electronic assemblies of the future. The trend in electronics manufacturing is not only towards miniaturization, but also towards large, highly integrated assemblies, for example for control centers or LED lighting technology. This is where the VERSAFLOW 4 XL comes into play, which can solder big boards up to 610 x 1,200 mm (24 x 48 inches) safely and efficiently in top quality. With up to five heating zones and three VERSAFLEX modules (two pots each on two independent axes), the Ersa VERSAFLOW 4 XL has found a firm place in the Ersa product portfolio thanks to its flexible performance – 15 delivered and installed systems within only a few months prove this.

Some of the new handheld communication devices offer real challenges to the paste printing process. Normally, there are very small devices like 01005 chip components as well as 0.3 mm pitch uBGA along with other devices that require higher deposits of solder paste. Surface mount connectors or RF shields with coplanarity issues fall into this category. Aperture sizes for the small devices require a stencil thickness in the 50 to 75 um (2-3 mils) range for effective paste transfer whereas the RF shield and SMT connector would like at least 150 um (6 mils) paste height. Spacing is too small to use normal step stencils. This paper will explore a different type of step stencil for this application; a "Two-Print Stencil Process" step stencil. Here is a brief description of a "Two-Print Stencil Process". A 50 to 75 um (2-3 mils) stencil is used to print solder paste for the 01005, 0.3 mm pitch uBGA and other fine pitch components. While this paste is still wet a second in-line stencil printer is used to print all other components using a second thicker stencil. This second stencil has relief pockets on the contact side of the stencil any paste was printed with the first stencil. Design guidelines for minimum keep-out distances between the relief step, the fine pitch apertures, and the RF Shields apertures as well relief pocket height clearance of the paste printed by the first print stencil will be provided.

. Is the layout designed for the PIP process? If the PCB hole diameter is too big, it will require too much solder to fill it up. If it is too small, it is very difficult to fill the hole properly with paste during solder paste printing

. With the old method, the beads were either too thick, too thin, or overlapped, and the dots of paint were too big or too small. Sometimes the beads or dots were dragged across the surface, rendering the product unusable
