If wave soldering is preferred, we recommend using a no-clean flux wave soldering process, rather than a process that requires washing. The fluxing pr
4、ocess wave must be controlled so as not to have flux migrate inside the switch through the top of the housing. Good venting is required. No-clean flux vapors can enter the switch if adequate venting is not available. The vapors will condense on the internal contacts and become an insulator when they
5、 solidify. 2. “DO NOT INSTALL” COMPONENTS: Do not install the following components: R117 R125 C158 C142 D3-5 D11 D13 H2-3 J11 3. JACKS: All Jacks, including J1, J3-6 (21-00-6616), J2 (21-08-0002), J7-8 (21-12-0035), and J9 (21- 00-0014) must be mounted flush with the PCB and lined up with the silksc
6、reen outline within +/-1 degree of accuracy. ALL jacks are to be mounted on the TOP SIDE of the PCB. See Photo: 4. SD CARD SOCKET: J10 (21-18-0900) must be mounted flush with the PCB and lined up with the silkscreen outline within +/-1 degree of accuracy. The SD Card is mounted on the TOP SIDE of th
7、e PCB. See Photo: Make sure SD Card is flush before soldering to PCB. 05/30/08 Page 3 of 6 LINE 6 CONFIDENTIAL 5. HEADERS: H1 (21-20-0040) and H2 (21-20-0206), are to be mounted flush against the PCB. Confirm that header H1 is installed correctly by ensuring that pin 1 on the header (indicated by ar
8、row on header) lines up with pin one on PCB silkscreen (indicated by the square pad). Also, be sure H2 is installed on the BOTTOM side of PCB and is aligned with the silkscreen outline within +/-1 degree of accuracy. See Photos.

Be sure that the case of each regulator is lined up with the
10、silkscreen outline within +/-1 degree of accuracy. See Photo: 7. REGULATOR STANDOFFS: Securely install HEX STANOFF (30-12-0009 STANDOFF HEX .250 6-32 M-F 0.250-IN AL) at all regulators (U19-23) using Screw (30-00-0043) See Photo: Standoffs are not to size picture is for reference only. 05/30/08 Page

POTS: Be sure both horizontally mounted Pots (01-48-9208 and 01-48-9209) are installed flush to the PCB and are aligned with the silkscreen outline within +/-1 degree of accuracy. See Photo. 9. GROUND FINGERS: ALL grounding fingers are mounted flush against the PCB edg
12、e. They are mounted with their center clip hole on the BOTTOM side of the PCB. The “curl” of the grounding finger should curve toward the TOP SIDE (toward the jack). They should then be manually soldered on the BOTTOM SIDE. See Photos: BOTTOM SIDE TOP SIDE 10. CRYSTALS AND INSULATORS: Crystals Y1 (P
13、/N 11-00-1002) and Y2 (11-00-1001) are to be installed with insulator (30-15-0007) and must be mounted flush against PCB.

14、tion of all electrolytic capacitors. All radial lead capacitors are to be mounted perpendicular to the PCB within +/- 5 degree of accuracy. They are to be mounted as low as possible to the PCB without sacrificing the lead to package-body integrity. RTV should be added as shown in photos below. BOTTO
