A cost-effective method to reflow your bumped wafers
If you need to improve your productivity and lower your costs, then consider our fluxless Electron Attachment solution, which uses non-flammable hydrogen and nitrogen blends to replace traditional flux chemistries for wafer-level packaging.
Gases
Air Products gases, typically provided in gaseous and liquid form, enable customers in a wide range of industries to improve their environmental performance, product quality, and productivity.
Hélium
Inert gáz kriogén, hőátadási, védő, szivárgásjelzési, analitikai és emelő célokra
Hidrogén
Reaktív és védő tulajdonságainak köszönhetően számos iparág használja fel - például elektronikai ipar, élelmiszeripar, üvegipar, vegyipar, finomítók - a minőség javítása, a teljesítmény optimalizálása és a költségek csökkentése érdekében.
Nitrogen
Useful as a gas, for its inert properties, and a liquid for cooling and freezing. Virtually any industry can benefit from its unique properties to improve yields, optimize performance and make operations safer.
Oxigén
Amellett, hogy lélegeztetőgázként alkalmazzák az egészségügyben, erős oxidáló tulajdonsága számos ipar számára nyújt előnyöket, mivel javítja a hozamokat, optimalizálja a teljesítményt, csökkenti a költségeket és kisebb ökológiai lábnyommal rendelkezik, mint a többi tüzelőanyag.

"We are experiencing poor underfill flow in our flip chip assemblies. What is the possible cause and is there a solution that can be implemented to improve our underfill process?"
Poor underfill flow is a common concern in flip chip assembly and is due to several issues. The predominate problem is contaminates left behind post reflow assembly. The primary contaminate is flux residue. Although you may clean the assembly post reflow, the likelihood of flux left behind is high. Most fluxes will polymerize during the reflow process in air or high O₂ ppm level (>500 O₂ ppm). Current cleaning processes may not be efficient enough to remove all the residue under the flip chip. The key is to use an inert atmosphere, such as nitrogen or argon, to eliminate high O₂ levels. The high O₂ levels will cause the flux to polymerize and be difficult to clean.
Best process practice is to use an O₂ ppm level of around 100 ppm. This will give you two benefits: (1) reduce the chance of flux polymerization and allow for good results post cleaning and (2) allow the flux to stay active longer increasing the fluxing properties to insure good wetting and provide a reliable solder joint.
Air Products can assist you in evaluating your processes and offer solutions to your concerns in this area.
