BEFORE HANDLING.

N.B. SNAP POWER TERMINALS INTO COMPONENT SIDE OF BOARD.

N.C. THIS AREA TO BE COVERED ON BOTH SIDES OF BOARD (WHERE

POSSIBLE) WITH SEALANT PRIOR TO ENCAPSULATION.

N.D. INJECT SEALANT ITEM 8 THROUGH THE PC BOARD TO SEAL MODULE LEADS

(16 PLACES), AND ALL COMPONENT LEADS ON THE NONO-COMPONENT

SIDE OF THE BOARD, THAT ARE COVERED BY MODULE CASE.

N.E. FEMALE EYELET TO BE AGAINST THE NON-COMPONENT SIDE AS SHOWN

EYELET MUST NOT SPIN AFTER CLINCHING.

N.F. SOLDER EYELET SO THAT SOLDER COVERS ENTIRE EYELET

AND ALL AROUND EYELET ON COPPER SIDE ONLY.

NO ICICLES OR SOLDER BLOBS PERMITTED.

N.G. AFTER SOLDERING, INSPECT POWER TERMINAL CONNECTIONS

TO ENSURE SOLDER HAS PROPERLY WET COMPONENT SIDE PAD

ON A MINIMUM OF 3 OF THE 4 LEGS OF THE POWER TERMINAL.

N.H. BAR MUST BE FREE OF ENCAPSULATION MATERIAL ON BOTH SURFACES

AROUND MOUNTING HOLES AND ENTIRE LENGTH OF MOUNTING SURFACE.

ENCAPSULATION MATERIAL MUST NOT EXTEND BEYOND THE MOUNTING

SURFACE PLANE. (2 PLACES)

N.J. DO NOT COAT WITH ENCAPSULATION MATERIAL, TOP AND BOTTOM, .80 +/- .05” DIA.

N.K. PC BOARD HOLES TO BE FREE OF ENCAPSULATION MATERIAL AND SEALANT

FOR A DIAMETER OF .50” FOR THE LARGER HOLES, AND .25 FOR THE SMALLER

HOLES, BOTH SIDES OF BOARD. (4 PLACES).

N.L. THIS AREA TO BE COVERED ON COMPONENT SIDE OF BOARD WITH SEALANT

PRIOR TO ENCAPSULATION. MATERIAL MUST BE APPLIED FROM TOP TO

COMPLETELY FILL TO UNDERSIDE OF DEVICE. THEN APPLY SEALANT AROUND

BASE OF DEVICE.

N.M. THIS AREA TO BE COVERED ON OPPOSITE COMPONENT SIDE OF BOARD WITH

ITEM 8 PRIOR TO ENCAPSULATION. DO NOT COAT WITH ENCAPSULATION

MATERIAL ON THE TOP SURFACES NOR THE THREADS.

N.N. THESE SURFACES MUST BE MAINTAINEDCO-PLANAR WITHIN .010” THROUGH

ENTIRE SOLDERING AND SEALING PROCESS.

N.P. SEALANT HEIGHT BETWEEN MODULES NOT TO EXCEED .17” MAX.
