WebThis time it got close enough to identify the package as a SOT363. Apparently they are simply transistors - the BC857 and BC847. See the section "Marking" on page 2 of each datasheet. The first one is a dual PNP, BC857BS by NXP. The second one is a dual NPN/PNP, BC847BPN, by NXP. Highly active question. WebWhite line printed on the IC, white line on the silkscreen to indicate direction. Some chips have a "knotch" at one end, that corresponds to knotch in the silkscreen and some have a dot in the corner of the ic, usually corresponding to a dot on the silkscreen. pubiclice9000 • …
What is the Orientation of Silicon Wafer 100, 111, 110?
WebThe text orientation is consistent, and for chips of this shape (with pins on two opposite sides), you can reliably assume that the polarity mark goes to the left of the text. Here are some classic and beautiful examples of … http://mjrnet.org/pinscape/BuildGuideV2/BuildGuide.php?sid=icchips dyson big bin service assembly

WebJul 18, 2024 · Joined: Jul 2024. RE: HP34C solderless chip orientation. I think Ren was referring to only the 2 smaller ones. Some versions have 2 and some have three. One is ROM for the C (constant memory) and the other two are RAMS. The ROM has a different numbering on the case and the RAMS have a similar numbering. WebUsed SMT Equipment Pick and Place/Feeders.

Qinyi Electronics Co.,Ltd. WebThe orientation marker on these chips is usually the "pin 1" dot, in the corner nearest pin #1. The chip in the photo above uses the indentation form of the dot, but yours might have a printed white dot instead. As always, the dot can be such a subtle indentation or faint ink mark that it's tough to see without a strong light and/or magnifying ... dyson big ball vacuum comparison
