SMD adhesive solves assembly problems
Delo-Monopox MK096 is a heat-cured, single-part epoxy resin optimised for high-speed SMT processes as well as manual processing.
Wave soldering and reflow processes are a special challenge for an adhesive that is used to fix SMD components on printed boards The reliability of many standard SMD adhesives decreases when used in conjunction with special forms, such as barrel-shaped melves, and critical materials such as glass

Wire bonding on a budget
The low-cost TPT HB10 bonder, configured for ball and wedge bonding, is suitable for low through medium volume production of microelectronic, microwave or photonic devices.
Now Delo has developed and tested an adhesive specifically for these requirements.
Together with renowned electronic customers, Delo has developed a new adhesive that ensures the reliable fixation of critical SMD components during wave soldering or reflow processes.
Delo-Monopox MK096 is a heat-cured, single-part epoxy resin optimised for high-speed processes as well as manual processing.
This adhesive is able to achieve a very high adhesion extremely quickly, especially on melves and glass substrates.
Within 60s, it has a shear strength of 25N.
And after 3min, when comparable products have reached approximately 10N, Delo-Monopox MK096 has a final shear strength of 70N.
In production this not only means that the cycle times are shorter, but also that the reject rates are significantly lower and less manual rework is required.
Due to the barrel-shaped geometry of the melves, there is only a small surface area available to bond.
Consequently, many standard SMD adhesives do not achieve the required strength for the subsequent soldering process.
This is where the new Delo adhesive displays its technical performance, which results in the significant reduction of reject rates.
Delo-Monopox MK096 can be easily processed on standard systems, eg Camalot or Asymtek, and integrated into automatic processing.
The adhesive can be jetted, dispensed from a cartridge or applied by screen printing.
The red colouring of the adhesive makes visual control of the application easier.
The adhesive drops on the printed board are reproducible and firm - even during jetting - because the viscosity of the adhesive has been specially adjusted.
Over 30,000 drops per hour can be dispensed.
The applied adhesive shows a universal adherence on different types of substrates.
This makes it a good all-rounder in the manufacture of printed boards.
