Let our material scientists and process engineers employ the right materials manufacturing technology to enhance your application's performance.
The manufacturing of Williams Packaging and Braze Products employs a wide range of methods to meet the varying needs of the marketplace. Internal casting, alloying, metal working processes, plating, stamping and machining are supported with experienced material scientists and craftsmen. Our innovative approach to what have become “standard” products, along with our value added services and new product developments, have made Williams an industry leader in micro electronic packaging.
Alloying and Casting
Alloying like casting is preformed in–house. Alloying starts off with precise weigh-up of materials meeting either standard or customer specifications, then cast with the proper method to yield the desired properties. Williams’ analytical lab monitors alloy levels and impurities.
Williams employs three methods of casting: static, vacuum and continuous casting. Each type of casting offers its own set of unique features and benefits. Static casting allows for flexible net shape and size, while vacuum casting is done in a completely controlled environment producing virtually void free material. Continuous casting allows casting close to net size, adding cost effectiveness.
The complete control of alloying and casting, along with our internal analytical lab, allows Williams' R&D team to develop custom alloys.
Metal Working Processes
Years of metal working and forming experience has allowed Williams to build comprehensive processes with stringent controls within our manufacturing facilities. Precision rolling, slitting, wire drawing hydrostic extrusion, and cladding methods are some of the metal working processes utilized at Williams to produce materials in the forms and shapes to meet customers' specifications.
Precision rolling of solder and braze materials allows for the control of material volume and produces quality surface finish. Hot rolling is essential in situations where the control of grain size is crucial. Traditional wire drawing is used for braze materials, but our Bonding Wire and Ribbon is hydrostatically extruded to eliminate minor surface imperfections. Cladding, which utilizes a combination of rolling and annealing, produces a product that consists of multiple layers of different materials.
Stamping and Machining
Square, rectangle, oval, special shape, flat or drawn, thin or thick, Williams has the operation to stamp or cut material to meet customer specifications. An extensive tooling library with over 8,000 blank, mult-up, or progressive dies are available. Our in-house Tool and Die Shop can build tooling to meet your specifications.
EDM machining is used for large or special shape performs and CNC machining for lids with complex profiles.
Plating
Whether it’s nickel or gold, or a combination of the two, our plating meets standard micro electronic grade material or Military Specs. Williams provides consistent coverage of electrolytic Ni, electroless Ni and soft gold. Rack and barrel plating methods are available. To insure plating quality, XRF methods are used to measure and control thickness, and accelerated corrosion testing is performed on each lot. Our in-house analytical lab regularly tests plating chemistry to ensure consistency from lot to lot.
Powder Atomization
Williams’ inert gas atomization tool was built and designed with flexibility as one of the key factors. Powder atomization lot sizes start at 25 oz and go up to 200 oz to meet the needs of both the custom production and R&D communities’ individual specs. Williams prides itself on producing solder and braze power with tight particle size distribution, low gas inclusions and uniform compositions.
