Just buy a separate machine to apply paste. You'll be able to run faster, (by doing more at the same time) and you can probably find an air-over-syringe system for less than $2000USD. At the end of the day, that's probably less than you'll spend in t

I'm currently working on bringing a manual coating process/workcenter online and my QA team is giving me some grief. For background, we're using Humiseal 1B31 thinned with thinner 521, mixed at 1:1 by volume. Spraying through a Binks HVLP with 10 P

Interesting, I work much the same way as Ivan up to the sticky tape part, plodding through the BOM against the pick and place file and downloading the relevant datasheets to verify packages, this can be tedious but usually gets much quicker the more

That's not really the point of dual lane feeders. As a general rule having a dual lane 8mm feeder means the machines "slots" are actually 16mm, dual lanes on a 8mm feeder helps keep the overall lane density of a machine higher, its much easier to bui

Rather than provide an endorsement of a particular brand, I'd like to give you some factors to consider in your selection: 1.) Bottom heater capacity and capability. The bottom heater is a key driver in a successful rework process. You want to even

Concerns about this machine: 1. It is very light - only 500kg. I will seriously doubt real speed of 7500cph. 2. 8 cameras???? Whatever the concept is, this is weird. imagine how a calibration of this toy will look like. 3. Feeder positions - only 6

What type of flux are you using today? - Obviously you have already outlined the difference in the parent materials and parent material preparation, so using the same program/profile will not work; the characteristics are different. Try increasing p

We are attaching 0.50mm diameter SAC 305 solder balls onto 0.38 diameter Au plated pins placed at a 0.80mm pitch (pins are pressed into a plastic insulator). A tacky flux is then stenciled onto the pins using a stencil with.a 0.38mm diameter aperture

All these generalizations are non sense. What real cph you will receive depend on many factors: - paths optimization - what number of feeders are used - what number of nozzle changes has your job - how fast is the recognition for small and big part

Thank you for your response. I'm new to SMT so I am constantly learning. Unfortunately have not come across books that go in detail about these issues (if I ever get time I might write one). I have an older universal gi-14d (7 spindle head, dual g
