Panasonic SPD Dual-Lane Screen Printer

Panasonic SPD Dual-Lane Screen Printer Description:

Dual Lane Screen Printing.

The SPD (screen printer dual) features high-speed simultaneous production of two boards of the same type or two completely different products. Non-stop model changeover capability allows changeover of one stencil while the other product is still running. And within its small footprint, the SPD's advanced squeegee reduces solder waste and prevents clogs while Panasonic's uni-floating printing method ensures excellent filling regardless of board asperity.

The SPD has two printing stages (front and rear sides). When two same type PCBs up to 350mm x 300mm are produced, it delivers productivity of 8.5s/PCB including average clean time.

Dual printing stage that furthers productivity

• High-speed production - Printing the same product on the front and rear printing stages enables the creation of a high-production line. Even for the single lane applied for the post process, the lane utilization can be enhanced by supplying PC boards from the front and rear stages.
• Nonstop changeover - The preparation for the next product can be carried out during one-sided stage production, thereby eliminating the time for changeover.
• Production of different types of PC boards - Printing different products on the front and rear printing stages help enhance utilization and avoid the necessity for intermediate stock.

Higher quality & higher productivity .  Further pursuing of high quality printing with "the cornerstone of quality is printing"

• Hybrid squeegee head - Owing to the motor control of vertical squeegee motions in addition to the uni-floating printing method, we have achieved a reduction in printing time and the prevention of air entrapped in the solder paste.
• Load detection unit - The printing head is mounted with the load detection unit to monitor the printing pressure during printing. Measuring the solder amount attached to the squeegee prevents solder amount shortages on the mask.
• PCB support function - The support plates, integrated with the conveyor rails, support the back side of the PC board from end to end, which realizes the stabilization of printing quality.

A variety of options that increase quality and productivity

• Automatic solder supply unit (option) - Automatically supplying (X-direction movable)solder onto masks enables a long period of continuous printing.
• Inspection result feedback support (option)* - According to the correction data of shifted printing analyzed by solder paste inspection (APC correction data), it corrects printing positions (X,Y,θ)
• Stencil height detection (option) - Laser processes can optimize a contact of PC boards with stencils so that stable printings can be provided
• Mask vacuum support mask-release (option) - Printing mask can be vacuumed during printing and support-table release. It can enable more stable rinting by eliminating shift and stick of a mask.
