HSOP package enables flow soldering
on a paper phenolic board whose demand is increasing for the reduction of PCB cost.
com) vice president of technology and SPVC chairman Karl Seelig, "Take Action Limits, also known as 'dump pot specifications,' are very important to any electronics manufacturing company using flow soldering
techniques either in selective soldering or wave soldering.
The separators' physical properties remain intact even when cell-drying temperatures rise up to 230 degrees C, or at flow soldering
conditions of 260 degrees C.
However, when using conventional soldering irons or flow soldering machines(*6), under filling of the through-hole can occur due to lack of heat or non-stable solder filling.
OKI's "static pressure soldering technology" successfully solders though-holes by controlling the solder liquid level to solve these flow soldering issues and by controlling the depth of dip(*8) of PWB.
Wave soldering, or flow soldering (as it was called in its early days), has been around for about 50 years (1).
The term flow soldering was a registered trademark of Fry's Metals.
If one wanted to work at about the same temperatures as used during flow soldering
, this yields the following calculation for eutectic SnPb solder:
