SPECIAL PRODUCTION NOTES
PCB ASSEMBLY DOCUMENTATION
ADD NUMBERS OF SPACERS YS# 8607 AND 9067 INDICATED
TO LEGS SHOWN FOR D201, Q206 AND Q207
PIC. 1
ADD 1 SPACER YS# 8607 TO MIDDLE
REAR LEG OF Q2 AS SHOWN
PIC. 2
ADD A #9067 SPACER TO THE MIDDLE LEG
OF Q1, Q3, Q6, Q7, D203 AND D220
PIC. 3
Bend these 2 leads on back of
board after inserting T1 (YS# 1226)
Bending the 2 leads indicated in Fig 1 should level
the XFMR T1 as shown in Fig 2 above
BOARDS PLACED UPSIDE DOWN ON RACK AFTER WAVE SOLDERING
AFTER WAVE SOLDERING, SOLDER SHLD 2 TO BOTTOM OF PCB WHERE SHOWN
9067
8607
9067
HAND SOLDER SHLD2 IN 4 PLACES
1. THERMISTOR R272 (YS# 6619) IS HAND INSERTED.
2. DO NOT STUFF COMPONENTS MARKED WITH DNS. IN THE LAYOUT PADS WITH
NO COMPONENT OUTLINE OR REF DESIGNATOR ARE ALSO NOT STUFFED.
3. ADD APPROPRIATE SPACERS TO LEGS OF XTRS AND RECTIFIERS AS INDICATD
IN PICS 1-3.
SEE ALSO PRE-ASSEMBLY NOTES
4. CUT LEADS SHORT ON ALL HAND PLACED TRANSISTORS.
5. NOTE THAT THIS BOARD USES A WAVE SHIELD THAT REQUIRES THE
SOLDER WAVE BE SET TO THE PROPER HEIGHT AND SPEED.
6. AFTER WAVE SOLDER. PLACE SHLD2 (YS#1668) ON BOTTOM OF BOARD AND
HAND SOLDER.
7. APPLY RTV WHERE INDICATED AND BETWEEN TALL COMPONENTS AND IN THE
HOLES PROVIDED. NOTE THAT L204 MUST NOT HAVE RTV APPLIED UNDER PART
UNTIL AFTER THE WAVE SOLDERING PROCESS AND IN THE HOLE ON THE
BOTTOM OF THE BOARD LOCATED NEAR U20.
8. AFTER WAVE AND PCB FINISHING, PLEASE PLACE BOARD ON RACK
WITH LARGE COMPONENTS FACING DOWN. SEE PICTURE
9. BEFORE TRANSPORTING TO WIRING PLEASE SEPARATE BOARD FROM PANEL
USING PIZZA CUTTER
THEN BREAKING NON SCORED END GENTLY WITH APPROPRIATE TOOL
INJECT SILICONE INTO COILS,
NOTE SILICONE MUST COME
OUT FOR A GOOD FILL
SILICONE IS ALSO INJECTED
FROM BOTTOM OF PCB, IT MUST
COME OUT UNDER PART.
RTV HOLE FOR L204 - SEE NOTE 7.
