Surface Mount Technology vs. Workstation Design

In today’s modern SMT assembly facilities, the design and flexibility of the workstation is critical to maintain quality, workflow and ergonomics. Unlike the old, static, welded frame workbenches and workstations of the past that were never moved or reconfigured, the … Continue reading

Will Juki-Sony Talks Get Others Going?

Industry chatter has long said M&A activity among the major placement companies is inevitable. Yet throughout the gut-wrenching downturn of 2001-02, the widespread pause in 2008-09, and the subsequent fallout starting last spring, nothing concrete took place. Sure, a few … Continue reading

Counting Once, Counting Twice…

Let’s say you have two options: First, you could send in your boards for assembly as individuals. Second, you could send them in a panel. That’s all fine and dandy. For a few, send individuals. For a bunch, panels might … Continue reading

Ambiguity

It’s pretty important to have unambiguous polarity markings and pin one markings printed on your PCB. In theory, for SMT parts, it really shouldn’t matter; the centroid would take care of the placement orientation. But, you may have noticed that … Continue reading

Through-Hole Parts

Screaming Circuits uses machines to place surface mount parts; even if it’s just one board. Through-hole is a different story, though. Way back in the cobwebby section of the building, we do have a through-hole part sequencing and insertion machine. … Continue reading

How to Build a Footprint

Well, not really how to build one in a technical sense, but some thoughts on how to better ensure that you get it right. In theory, it shouldn’t be that difficult. You download the datasheet and build the land pattern … Continue reading

Electricity Use in Pb-Free

Folks, An obvious disadvantage of lead-free electronics soldering assembly is that the oven must be hotter and therefore will use more electricity (versus SnPb37 soldering). But is the extra amount of electricity significant? KIC’s Brian O’Leary claims that a typical SMT … Continue reading
