Service notes

Leadless chip component
(surface mount)

Chip components must be replaced with identical chips
due to critical foil track spacing. There are no holes in
the board to mount standard transistors or diodes.
Some chip capacitor or resistor board solder pads may
have holes through the board, however the hole
diameter limits standard resistor replacement to 1/8
watt. Standard capacitor may also be limited for the
same

reason.

It

is

recommended

that

identical

components be used.
Chip resistor have a three digit numerical resistance code
- 1st and 2nd significant digits and a multiplier. Example:
162 = 1600 or 1.6k

resistor, 0 = 0

Ω 

(jumper).

Chip capacitors generally do not have the value
indicated on the capacitor. The color on the component
indicates the general range of the capacitance.
Chip transistors are identified by a two letter code. The
first letter indicated the type and the second letter, the
grade of transistor.
Chip diodes have a two letter identification code as per
the code chart and are a dual diode pack with either
common anode or common cathode. Check the parts
list for correct diode number.

Component removal

1.

Use solder wick to remove solder from component
end caps or terminal.

2.

Without pulling up, carefully twist the component
with tweezers to break the adhesive.

3.

Do not reuse removed leadless or chip components
since they are subject to stress fracture during
removal.

Chip component installation

1.

Put a small amount of solder on the board soldering
pads.

2.

Hold the chip component against the soldering pads
with tweezers or with a miniature alligator clip and
apply heat to the pad area with a 30 watts iron until
solder flows. Do not apply heat for more than
3 seconds.

How to replace Flat-IC

- Required tools -

1.

Cut the pins of the defective IC with the wire cutter
pliers, and remove it completely away from the
board. If the IC is glued to the board, apply hot air to
complete the removal. CAUTION- Do not pull or
twist the pliers, it may damage the soldering pads in
the board .

2.

Using the soldering Iron and the long nose pliers,
remove the IC pins that are still attached to the
board.

3.

Using the de-solder braid and the soldering Iron,
remove the solder from the board soldering pads.

4.

Position the new flat IC in place (apply the pins of
the flat IC to the soldering pads where the pins need
to be soldered). Properly determine the positions of
the soldering pads and pins by correctly aligning the
polarity symbol. Start aligning and soldering Pin
No.1, then align and solder the pin in the apposite
corner of the IC, this will help to align the rest of the
pins.

5.

Solder all pins to the soldering pads using a fine
tipped soldering iron.

6.

Check with a magnifier for solder bridge between
the pins or for dry joint between pins and soldering
pads. To remove a solder bridge, use a de-solder
braid as shown in the figure below.

Note: These components are affixed with glue. Be careful not to break or damage any foil under the

component or at the pins of the ICs when removing. Usually applying heat to the component for
a short time while twisting with tweezers will break the component loose.
