(2)
- Mannix TSC1210 belt furnace
- Loctite Zeta Model 7050A UV curing station
- American Ultra Violet belt furnace
- Dage BT22-PC die shear tester
Soldering operations
Soldering operations are housed in a class 100K clean room. Soldering processes utilizing low temperature eutectic tin/lead solder, high temperature tin/lead solder and lead free solder have been qualified.
Solder dispense:Each working bench is equipped with an EFD dispense unit.
- A Weltek screen printer Model 44 is used for volume dispense of
solder paste.
Solder reflow
- Each working bench is equipped with a Weller manual soldering
station.
- Micro-flame reflow station fueled by a hydrogen generator SAT model
205HP is used for high temperature reflow and localized reflow.
- Continuous reflow is provided by belt reflow furnaces. All belt
furnaces reflow solder in nitrogen atmosphere. Liquid nitrogen is used too provide clean gas, humidity and oxygen free atmosphere.
- Sikama 4-zones conduction belt furnace with controlled atmosphere
- RTC 6" 1-zone radiant heat belt furnace Model 206
- BTU 2.5" 3-zones forced convection belt furnace with controlled
atmosphere
- Watkins Johnson 12" 10-zones forced convection belt furnace with
controlled atmosphere and oxygen monitoring
Surface cleaning
- Baron-Blakeslee Model MLR-120 spray degreaser is used to remove
residual flux when high temperature solder is used. A stabilized, halide free solvent, Ensolv is used.
- Ionox FCR is used as water soluble solvent. The wet station is
composed of an ultrasonic cleaner followed by rinsing in Iso-Propyl alcohol and de-ionized water. Drying is performed in cold air.
Inspection & Test station
- Bausch & Lomb stereo microscopes are used for visual inspection
- Nikon Optiphot microscopes with magnification to 200x are used for
failure analysis
- Multimeters and power supplies are used for electrical testing of
circuits.
Other Peripheral equipment
- Lead frame singulation
- Lead frame trim & form station
- PCB singulation
- Heat seal tape attach system
- Fine & gross leak detection system
Micro-Post
The “Micro-Post” is a totally novel method for connecting semiconductor devices onto a wide range of circuit board materials. The mPost is attached directly onto standard, wire bond pads and can be manufactured from any of the materials normally used for wire bonding.
Customizing
The shape of the Micro-Post can be customized, for each application, to optimize electrical performance and mechanical reliability and will allow semiconductor die, with <150 m pitch pads, to be flipped directly onto FR4, without the need for an underfill.
Cost Effective
The Micro-Post process is extremely cost effective and can be carried out on individual die, either at the wafer level or after singulation. The unique manufacturing methodology can even accommodate full electrical testing, including Burn-In.
Techniques
Once Micro-Post the die can be attached using a wide range of techniques; Thermocompression and thermosonic bonding, reflow soldering and conductive, z-axis and even non-conductive adhesives. The tapered tip provides for easy alignment and will also accommodate undulating surfaces. It is even possible to socket the part.
