Topic 4 of a Spanish mobile repair course, explaining how to identify the parts of a smartphone, as a 404 KB PDF identical in size to the unnumbered copy.

Spanish training PDF on identifying the parts of a smartphone, describing the main components and modules found inside a typical handset.

The 3N253 is documented in this 42.2 KB PDF, categorised as a schematic but evidently a discrete-component datasheet.

Circuit diagram for a Sony laptop mainboard identified as GD1A, supplied as a PDF of about 733 KB.

Catalogued as a schematic, 33C704 is a 166 KB PDF whose name is just an alphanumeric code without any model, manufacturer or board revision.

Schematic archive for a board identified as 71RA14RM6-T820 with A14RM and A14RMXX references at REV1.0, a 1.12 MB RAR containing the PDF.

Second schematic copy for the Toshiba Tecra A11, carrying the same FHNSY1, DPL99060G01 and A5A002688010 identifiers, at a slightly larger 1.86 MB in PDF format.

Compressed schematic package for the Lenovo ThinkPad T410i, with the name listing NZ0MI-1 and nzm41-8 as board or project identifiers.

PDF schematic for Apple logic board 820-2997, stored in an 841 KB RAR archive. The 820-xxxx number is Apple's own logic board identifier and appears printed on the PCB…

Schematic in PDF form whose name is only a random identifier string, so it reveals nothing about the device, brand or board number.

Datasheet-like PDF of 116 KB covering the 2SC3638. Under JIS semiconductor naming, 2SC identifies NPN bipolar transistors.

PDF document of 275 KB for the 2N5883, with an RE suffix the name does not explain, possibly a revision marker.

Reference PDF for the 2SD1065, 119 KB, filed in the schematic category although the name identifies a single transistor and points to a datasheet.

PDF of 135 KB for the 2SC5277, filed as a schematic but most likely a transistor datasheet, as 2SC is the JIS prefix for NPN bipolar devices.

Datasheet PDF of 41.4 KB for the 2SA1249, placed among schematics in this index. The filename holds only the component number, and the 2SA prefix identifies a PNP…

Catalogued under schematics, a 147 KB PDF carrying just the part code 2N6756. No model, board number or revision appears in the name.

Document for the 2SD2536 transistor, a 71.6 KB PDF in the schematic category that is most likely its datasheet.

Named only for the 2SK2074, this 95 KB PDF is catalogued as a schematic but is most likely the transistor's datasheet.

Reference PDF of 178 KB for the 2SC4682. Although catalogued as a schematic, the part number uses the Japanese JIS scheme where 2SC identifies an NPN bipolar transistor…

PDF reference, 140 KB, for the 2SC4486 NPN bipolar transistor, identified as such by the JIS-standard 2SC prefix. The name provides only the part number.

Indexed under schematics, this 112 KB PDF carries the part number 2N6504, a designation from the JEDEC 2N registration system for discrete semiconductor devices.

Named simply for part 10YQ045, this 48.3 KB PDF is best read as a component datasheet rather than a board drawing.

Reference PDF for the 2SD1453 transistor, catalogued as a schematic though the name points to a part datasheet.

Datasheet for the 2SK2968 in a 405 KB PDF, categorised with schematics but describing one discrete device.

Reference PDF for the 2SD1197 transistor, 134 KB in size and indexed as a schematic, though the file name is only a part number and reads as a datasheet.

Datasheet-type PDF for the 2SC3912, sized at 30.2 KB. The part number follows the JIS standard, where 2SC identifies an NPN bipolar transistor; the name offers no…
