SmartHeat Technology

Savvy electronic production engineers define

success by how they maximize their

productivity, yield, and product reliability. All

of these factors depend directly upon process

control. To achieve success, OK International

has developed SmartHeat conduction

soldering systems which uniquely sense the

exact thermal requirement for each solder

joint and respond by delivering the precise

amount of thermal energy at the rate required

to create a reliable connection. The result is a

high degree of control without resorting to

higher tip idle temperatures required by

conventional ceramic heater technologies.

Consequently the risk of component / board

damage is minimized, especially important

with the greater thermal demands required by

lead-free applications.

As you'll see below, SmartHeat provides

unique benefits in the delivery of high

reliability low risk conduction soldering

solutions, especially with lead-free alloys. All

of these add up to provide a highly consistent

level of process control.

SmartHeat® Delivers Direct Power

First and foremost, the success of conduction soldering depends upon the

availability and controlled flow of thermal energy into the connection during

the two critical phases flux activation and intermetallic bond formation. Lead-

free alloys, with higher thermal demands, further heighten these

requirements. Conventional ceramic heaters attempt to control this process

by managing indirect parameters, such as the tip idle temperature. In contrast, SmartHeat technology senses the specific

thermal demand directly at the solder pad and delivers the precise quantity and flow of thermal energy during both phases to

ensure a reliable connection.

Precision Tip Selection – The Conductivity Factor

During the execution of a successful soldering connection, the tip is the thermal energy “highway” from the heater to the pad and, therefore, the choice of tip geometry is critical to prevent power losses. In addition to providing the most thermally efficient tip designs, OK International has pioneered the tip “Conductivity Factor” rating system providing operators with quantifiable guidance in the selection of the optimum tip geometry. Additionally, our proprietary Power Meter can quantify exact pad energy requirements, further refining the tip selection process. Lead-free alloys, with tighter thermal demands, make these tools mandatory.

operator set point controls.

Each of these elements is

subject to drift and instability requiring frequent calibration and certification to ensure compliance. By contrast, the repeatability of

SmartHeat technology is inherently determined by the molecular properties of the heater material and does not shift over time,

ensuring long term stability without the need for calibration.

Reduced Risk of Overshoot

Conventional soldering stations strive to control the process with tip temperature using thermocouple sensors and ceramic

heaters. Inherent with this technology will be significant temperature variances throughout the tip body and consequently thermal

overshoot/undershoot. The risk is unreliable solder connections or damaged components. SmartHeat technology, on the other

hand, detects and controls the energy requirement of the pad, avoiding thermal delivery variances thereby eliminating the risk of

component damage.

Perfect for Lead-Free

The steps required for reliable lead-free

connections parallel those for traditional

alloys except that the thermal demands

are greater. The typical operator response

to the higher thermal demand is to

increase tip idle temperature,

unfortunately at higher temperatures the

contribution to thermal performance is

negligible. More importantly, the increase

in tip idle temperature comes dangerously

close to component and substrate

damage levels making process control

critical. Compared to conventional

our Precision Tip Selection tools delivers precise process control assuring consistently reliable connections at low operating

temperatures which provide the thermal performance necessary for lead-free.

Increase Tip Life and Value

The useful life of a tip is dependent upon many factors including flux corrosion, oxidation and tin dissolution. With higher tip idle

temperatures, the contribution from these factors is dramatically increased. The resultant de-wetting from these chemical surface

interactions causes many operators to increase tip force, which significantly accelerates tip life deterioration. With the advantages

of SmartHeat technology operators can solder at lower temperatures and, combined with proper tip selection and care,

dramatically extend tip life and value.

MFR Multi Function Rework Systems

The All in One Solution

Imagine performing all of your production soldering, rework and desoldering tasks with just one tool. The new Multi Function

Rework Systems (MFR) not only expertly perform rework, they also have tools for SMT and through-hole soldering. These flexible

systems feature two switchable outputs with a comprehensive choice of tools that support today's complex PCB and component

technologies.

Systems are configured with the following tools:

 Soldering and Rework  Production Soldering  Adjustable Desoldering Hand-Piece

 Standard Tweezer  Precision Tweezer

Perfect for Lead-Free

The MFR Series uses SmartHeat Technology to

deliver the power required for lead-free

connections. SmartHeat Technology’s variable

power instantaneously senses and continuously

delivers the precise thermal energy to the pad,

yielding high quality solder joints while protecting

sensitive components from damage.

Tip and Cartridge Options

With the MFR Series you can use heater tips or tip cartridges,

each filling a specific need. Heater tips are cost effective to meet

the demands of point to point, production soldering. While tip

cartridges are suited for high performance and rework

applications. Both options incorporate the popular quick change

design OK tips are well known for, which eliminates the

maintenance associated with traditional irons. The OK cartridge

tip has the slimmest diameter allowing access to the tightest

applications and its single piece design provides a secure

ground connection protecting sensitive components.

Versatility, Performance and Value

These high performance systems can be adapted to your exact

needs, whether it is cost effective production soldering, more

complicated rework with cartridges, handling small components

with the unique Precision Tweezer hand-piece or performing

through-hole desoldering.

All units include "Auto Standby" and "Auto Off" functions which

can be programmed to activate on different timing to help save

tip life, especially when working on a lead-free process.

Proprietary built-in motion detection then brings the unit back to

life when the operator lifts the hand-piece from the cradle. In

addition, a specially designed lead-free workstand provides

efficient tip cleaning and maintenance options.

And, when multiple units are used on the same bench or for the

same process, smart mechanical design allows for the units to

be interlocked, maximizing bench space.

Comfort and Simplicity

The short tip-to-grip distance of the MFR hand-piece improves

process precision for fine pitch applications. The cartridge

system provides the slimmest shaft for maximum access whilst

the precision tweezer design enables rework of the smallest

chips and resistors, such as 0201 chips. Ergonomic design

delivers superior performance with operator comfort and control.
