Operation Notes
Applications
Chip resistors are designed for general electronic devices
such as home appliances, computer, mobile communications,
digital circuit, etc. If you require our products with high
reliability-performing at more than 125℃ or below -55℃- for
medical equipments, aircraft, high speed machines, military
usage, and items that can affect human life or if you need to
use in specific conditions (corrosive gas atmosphere), please
contact us beforehand.
Normal operation temperature ranges (℃) as follows.
-1608, 2012, 3216(general, precision) : -55℃~+155℃
-Others (rectangular, array, trimmable) : -55℃~+125℃
Although resistor body is coated, sharp excessive impact
should be avoided to prevent damages and adverse effects
on characteristics (resistor value, open circuited, T.C.R.).
Example of Land
Pattern Design
Storage
To maintain proper quality of chip components, the following
precautions are required for storage environment, method and
period.
Storage Environment
- Make sure that the ambient temperature is within 5℃~40℃
and the ambient humidity is within 20~70%RH.
- Chip components may be deformed, if the temperature of
packaged components exceeds 40℃.
- Do not store where the soldering properties can be
deterio rated by harmful gas such as sulphurous gas,
chlorine gas, etc.
- Bulk packed chip components should be used as soon as
the seal is opened, thus preventing the solderability from
deteriorating.
- The remaining unused chips should be put in the original
bag and sealed again or store in a desiccator containing a
desiccating agent.
Storage Time Period
Stored chip components should be used within 6 months
after receiving the components. If 6 months or more have
elapsed, please check the solderability before actually using.
Abstract
When designing P.C.B, the shape and size of the solder lands must allow for the proper amount of solder under the resistor.
The amount of solder at the end terminations has a direct effect on the probability that the chip will crack.
The greater amount of solder, the amont of stress on the chip, and the more likely that it will break.
Use the following illustrations as guidelines for proper ‘solder lands design’.

Cleaning
Soldering
Our products have Ag electrodes protected by double layer.
1st Ni coating
- This prevents Ag electrode from leaching and enhances the
bonding with Sn.
2nd Sn coating
- This is made of Sn 100% with melting point 232℃ to prevent
it from melting when solder cream melts, and to enhance
the bonding. Commercial solder creams are made of
Sn-3.0Ag-0.5Cu with melting point 217℃.
After Soldering Cleaning, soldering flux & Ionic cleaning
liquid should be avoided on product.
If any possibility on product, please take a test before usage.
Caution for Chip Resistor
Seperation from PCB.
Chip resistor installation on PCB is similar phenomenon on
chocolate chip on top of cake.
PCB has enough flexibility on outer force but Chip resistor
can be defected without any bending.
(By chip resistor use of Ceramic, solder, metal)
Therefore, when separate from Chip resistor on PCB, be ware
of any crack of chip.

Recommended Soldering
Conditions
Abstract
There are 3 soldering methods.
- Flow(wave) soldering.
- Reflow soldering. (Reflow soldering is broadly divided into the total heating method and local heating method.)
- Iron soldering.

Reflow Soldering
Pre-heating and cooling
In the reflow soldering method, a full pre-heating at the proper
temperature is necessary to dry and activate solder paste.
Tomb-stoning can be reduced by preheating at 150~180℃ for
more than 1 minute. Also when cooling is done by dipping into
solvent, care should be taken to keep the temperature difference
within 150℃.
Standard Reflow Soldering Condition
Soldering must be carried out without exceeding the approved
soldering temperature and time shown within the shaded area
of the right graph. This prevents the terminations from leaching
and characteristics from deteriorating. When soldering is
repeated, the allowed time is the accumulated time.
Standard solder amount
When a PCB is warped, mechanical stress applied to the chip
should be reduced, and for doing so, care should be taken not to
use excessive amount of solder on the PCB. In case of the reflow
method, the thickness of the coated solder paste is controlled to
prevent excessive solder. The thickness of solder paste should be
100~300㎛.

Iron Soldering
Since Chip resistors come into direct contact with melted solder during soldering, it exposed to potentially mechanical stress caused
by the sudden temperature change. The chip resistors may also be subject to silver migration, and to contamination by the flux.
Because of these factors, soldering technique is critical.
Tombstoning and Prevention
When reflow soldering, or especially vapor phase soldering (VPS), small chip components of less than RC3216 type may break
away from solder and stand on end. This is commonly known as tombstoning or the Manhattan phenomenon.
Flow(wave) Soldering
Features
There are two types of soldering methods in flow(wave) soldering.
One is single wave soldering, the other is a double wave soldering.
However, double waves soldering is mainly used. This method is
designed so that the continuous and multiple dipping processes
by waves of solder having completely different primary and
secondary characteristics and waveforms.
With the primary wave, a comparatively strong jet flow is used
to remove the flux gas and to solder.
With the secondary wave, it is used to remove excessive solder.
With the primary wave, the solder flows into a very small gap
between components and air bubbles remaining on the soldered
joint are removed.
With the secondary wave, the peel back is used to prevent bridging.
PCB
solder
- Cause of tomstoning
PCB: Form and size of land, component layout and material
Chip component: Form, size, weight and solder wetting properties
Solder paste: Particle form, particle diameter, degree of activation and coated amount
Machine: Pre-heating condition, unbalance heat system and mechanical vibration
- Preventing tombstoning
Keep land size as small as possible.
Pre-heat (Pre-heating temperature: 150~180℃, Pre-heating time: More than 1 minute )
Keep the amount of solder paste low.
Keep position deviation at a minimum when mounting chips.
When soldering, reduce thermal unbalance at both electrode of a chip.

Preheating
Dipping
Cooling
If a chip component is heated suddenly during soldering, it may be
cracked by the thermal shock caused by the temperature difference
between the surface and the inside of the chip. To prevent this, a full
preheating is necessary. In case of wave soldering, the temperature
difference between solder and surface of the component is kept within
150℃. Also when cooling is done by dipping into solvent, care should be
taken to keep the temperature difference within 150℃.
Standard Soldering Condition
Soldering must be carried out without exceeding the approved soldering
temperature and time shown within the shaded area of the right graph.
An excessively long soldering time or high soldering temperature results
in leaching of the outer terminations.
When a PCB is warped, mechanical stress applied to the chip will be
increased and might be a cause of chip crack, especially if there is big
amount of solder on the chip. So, care should be taken not to use excessive
amount of solder on the PCB. For the flow(wave) soldering, the solder
amount can be controlled by land size.

When using a soldering iron or any other soldering operation, the permissible temperature and time should not be exceeded
that in the reflow soldering. In other to prevent the external terminations from leaching and characteristics from deteriorating,
the tip of the soldering iron should not touch the chip component (ceramic element, resin case, etc.). Soldering with a soldering
iron and correcting with a soldering iron can be performed right the following conditions.
