Speedline Technologies has released lead-free enhancements for its Electrovert Econopak Gold Wave Soldering Systems.

Designed for medium volume electronics manufacturers, the systems ship lead-free process ready.

The compact wave soldering solution now has UltraFill Nozzles and a Quick Change Solder Pot.  

Nozzles are 40% percent wider than the traditional tin/lead nozzle. Their design and placement mean less superheat is required to reflow solder joints in the second wave. Benefits include improved hole fill, bridge defect reduction and reduced dross formation. Available in Melonite Corrosion Resistant Stainless Steel or Titanium material. 

An optional Nitrogen shroud encompasses the nozzles in the pot. It allows for air or nitrogen operation and lift design ensures ease of maintenance and dedrossing without change or removal.

Solder pot allows for the easy switch between alloys such as tin/lead and lead-free solder.  The unit includes a second solder pot with motors, pumps, flow ducts, nozzle and two trolleys.

The lead-free ready platform can be fitted with many features including nitrogen inerting, convection pre-heating, Rotary chip wave, gas knife de-bridging technolog, and alternate fluxing options. The solder module provides wave dynamics for densely populated circuits, SMT components and difficult-to-solder geometries. Processes boards up to 400 mm with 1.2 m of preheat.

The latest upgrade to the VISULA PCB design environment reportedly enables users to integrate with the firm’s high-speed design solution, CR-5000 Lightning. Users can now take advantage of CR-5000 Lightning’s high-speed routing and simulation technology to explore different design scenarios and signal integrity trade-offs.
 
The upgrade is  free of charge for all VISULA and former Hot-Stage customers with a current maintenance agreement and for those existing VISULA users purchasing a new license of CR-5000 Lightning.

Zurich, Switzerland -- DEK has developed a high-throughput backside wafer coating process, which is hosted on a mass imaging platform capable of exceeding the +/- 12.5 um total thickness variation (TTV) required by most wafer processing specialists. The process is compatible with underfill or adhesive-type coatings which are normally applied at a nominal 50 m thickness to the backside of semiconductor wafers prior to singulation.

“For any backside wafer coating process, TTV is the critical success factor,” said Clive Ashmore, global applied process engineering group manager. “With this latest application advancement, we are helping semiconductor packaging manufacturers increase throughput and reduce the cost per package by using high accuracy mass imaging.”

According to the company, the use of an optional wafer handler, flexible printing platform and reflow oven achieves more flexibility than dedicated backside coating machines. The system can be re-deployed for other processing requirements.

The backside wafer coating process is compatible with the company’s metal stencil and emulsion screen technologies. Metal stencils enable materials with larger filler particles, such as encapsulation materials, to be applied with a totally smooth surface finish. Mesh stencils allow other materials such as thermoplastic adhesives to be deposited accurately and at high speed. In each case, the capabilities of the machine and stencil technology are key to achieving control over the print thickness and ensuring uniformity at high volumes.
