The FT-847is carefully designed to allow the knowledgeable operator to make nearly all ad- covered by warranty. For the major circuit boards, each side of the board is identified byiV/ the type of the majority of components installed on that side. In most casesone side has only chip components, and the other has either a mixture of both chip and lead components (trimmers, coils, electrolytic capacitors, packaged ICs, etc.), or lead components only. While we believe the technical information in justments required for various stationconditions, modes and operator preferencessimply from the controls on the panels, without opening the case of the transceiver. The FT-847 Operating Manual describes these adjustments, plus certain in- this manual is correct, Yaesu assumesno liability for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical information would be ternal settings. Servicing this equipment requires expertisein handling surface mount chip components. Attempts by unqualified persons to service this equipment may result in permanent damage not appreciated. Yaesu Musen reserves the right to make changes in this transceiver and the alignment procedures, in the interest of technological improvement, without notification of owners.

The first one placesa small spot of adhesive resin at the location where each part is to be installed, and later robots handle and place parts using vacuum suction. For single sided boards, solder pasteis applied and the board is then baked to harden the resin and flow the solder. For double sided boards, no solder paste is applied, but the board is baked (or exposed to ultra-violet light) to cure the resin before dip soldering. In our laboratories and service shops, small quantities of chip components are mounted manually by applying a spot of resin, placing the components with tweezers, and then soldering by very small dual streamsof hot air (without physical by first contact removing duringsolder soldering). using aWe vacuum remove suction parts ,j Precautions for Chip Replacement 0 Do not disconnect a chip forcefully, or the foil pattern may peel off the board. 0 Never re-use a chip component. Dispose of all removed chip components immediately to avoid mixing with new parts. 0 Limit soldering time to 3 secondsor less to avoid damaging the component and board. Removing Chip Components 0 Remove the solder at eachjoint, one joint at a time, using solder wick whetted with nonacidic fluxes as shown below. Avoid applying pressure, and do not attempt to remove tinning from the chip's electrode. , - ~-~ ~ iron, which applies a light steady vacuum at the iron tip, and then breaking the adhesive with tweezers. 0 Grasp the chip on both sides with tweezers, Special vacuum/ desoldering equipment is recommended if you expect to do a lot of chip replacements. Otherwise, it is usually possible to remove and replace chip components with only a tapered, temperature-controlled soldering iron, a set of tweezers and braided copper solder wick. Soldering iron temperature should be below 280°C (536°F). and gently twist the tweezers back and forth (to break the adhesive bond) while alternately heating eachelectrode. Be careful to avoid peeling the foil traces from the board. .Dispose of the chip when removed. 0 After removing the chip, use the copper braid and soldering iron to wick away any excess solder and smooth the land for installation of the replacement part. C'c f 1-4 FT -847 Technical Supplement -Chip Installing Component Information a Replacement Chip As the value of some chip components is not indicated on the body of the chip, be careful to get the right part for replacement. 0 Apply a small amount of solder to the land on one side where the chip is to be installed. Avoid too much solder, which may cause bridging (shorting to other parts). 0 Hold the chip with tweezers in the desired position, and apply the soldering iron with a motion line as indicated by the arrow in the diagram below. Do not apply heat for more than 3 seconds. 0 Remove the tweezersand solder the electrode on the other side in the manner just described. 1-5 FT -847 Technical Supplement T -Exploded View & Miscellaneous ':, Parts RAOO70000 S4000045 REI::: -~ ___=~De~cription PAN HEAD SCREW -~:~- Y~~U00200iXI1 M2.6x6 PAN HEAD SCREWM3xB UOO3OBOO1 14 <3> PAN HEAD SCREW UOO330001 4 @ PAN HEAD SCREW M4x6B U00406007 2 <5> SEMS SCREW ASM3x6 UO3300001 8 @ (1) BINDING HEAD SCREWM2x4B BINDINGHEADSCREWM3x6 U20104007 U20306001 1 3 @ TAPTITE U24306001 83 @ TAPTITE SCREWM3xB <8 OVAL HEAD SCREW @ SCREW M3x6 U243OBOO1 9 U31406007 2 OVALHEADSCREWM4x1OB U31410007 4 @ OVAL HEAD SCREW U31416007 2 @ TAPTITE SCREW U34306001 4 @ TAPTITE SCREWM3x6 @ TOOTHED @ HEX HEAD BOLT HSM4x16NI @ BINDING M4x6B M4x16B M3x6 LOCK WASHER OW4NI HEAD SCREW M3x1B M3x2ONI Non-designated only as part of (Lot 8-) parts are a designated (Lot 3-) 9!¥-:4 <2> M3x30 RAOO7000A TOPCA E U44306001 8 U72004002 1 U9900076 1 U20318001 U20320002 4 @ R4150130 HANDLE HOLDER (2pcs) t B-) available assembly. @ V/U-PA Unil D ) RAOO6300A RAOO63000 RUBBER (Lot 4-) (SP) KNOB (MODE) RA00651 00 KNOB (POW) RA0065200 KNOB (MOX) RA0063300 RA006330A (Lot 4-) RUBBER KNOB (TU) ) 17-) ~@ @ "'"./ RA0063200 RA006320A RUBBER (Lot KNOB 4-) (ME) AF-GNTL Unit RA0070100 ./" RAOO7010A (Lot. 3-) IS\ BOTTOM CASE ~ RA00631 00 RA006310A (Lot 4-) RAOO72400 RUBBER KNOB (KEY) COIL SPRING RA0065500 ENCODER KNOB (2pcs) RAOO63400 RAOO65600 RAOO6340A (Lol. 4-) VOLUME KNOB RUBBER KNOB (CL) RAOO64800 RA0070300 KNOB MAIN ASS'Y SHEET (SAT) RAOO65900 KNOB (SHUTTLE) RA0065400 KNOB (OUT) (4pcs) RAOO65300 RA006530A (Lol. 4-) KNOB (IN ) (4 pcs) R3100700 R3100700A (1.01. 12-) FOOT (2pcs) FT -847 Technical Supplement 2-1 '::~:;';;:~iii!L Exploded REF. i J. i I View & Miscellaneous DESCRIPTION C 0001 AL.ELECTRO.CAP.
