FRANKLIN, MA, Nov. 15 - The MPM Accela screen printer has a completely new design and operator interface, and reportedly delivers raw throughput gains of 20 to 30%. This is aided by a parallel processing setup in which all axes move simultaneously. The machine is designed for applications such as cellular phones and automotive.
The new platform is said to
- Reduce setup, changeover and consumable downtime (to 5 minutes from 20), and features tool-free hardware interfaces
- Deliver equipment robustness, ease of operator use, and a module level design with CanOpen controls, with no tools needed to switch from pumps to blades.
- Feature easy service, support, and upgrade capability, all within the same footprint as previous MPM printers.
- Offer 0.0005" accuracy for alignment and repeatability, and 0.001" print accuracy.
- Handle higher density, more complex boards as well as lead-free manufacturing requirements.
- Board sizes handled are 2 x 2" to 20 x 20", and thickness of 0.15 mm to 12.7 mm and up to 7 kg (15 lbs.).
The printer has been awarded two U.S. patents, and nine others are patent-pending.
ALPHA EF-8000 lead-free no-clean wave solder flux claims to provide excellent first pass yields, worry-free in-circuit testability and excellent electrical reliability in lead-free and tin/lead wave soldering applications. IPC rated ROL0, exceeds the Bellcore and JIS standards for electromigration and surface insulation resistance, as well as more stringent electromigration and bulk insulation resistance requirements from leading OEMs.
"ALPHA EF-8000 flux creates a new industry standard for broad latitude application, because it withstands the higher PWB surface temperatures required for successful lead-free soldering, but it is fully capable for use in standard tin-lead applications," said Mitch Holtzer, global product manager. "In addition, it can be qualified now for emerging lead-free requirements, and used in lead-free or tin lead production lines."
Low rosin content minimizes flux residue buildup on pallets and wave soldering equipment normally associated with high (>10%) rosin flux formulas.

RFS-20 constantly recycles rinse water from stencil and batch cleaners, saving water, energy and disposal costs. The fully automatic system constantly filters the rinse water and returns it to the stencil cleaner for re-use, eliminating the need for evaporators, haulage or in-house wastewater treatment facilities. A four-stage filtration system cleans the rinse water and returns it to the cleaner.
Three-way valve allows the rinse tank fluids to be power drained when changing fluids during periodic maintenance.
Filtration system consists of an in-line solder trap, a 10-micron polypropylene filter, an activated carbon powder filter to remove organics and a 5-micron polypropylene filter for fine particulates and organics. Rinse tank water is constantly re-circulated, extending the bath life of both the wash and rinse tank fluids in the cleaner.
