REFLOW SOLDERING MATERIAL, Solder paste is a combination of pre alloyed spherical metal powder and. flux medium,Solder paste,http engw eb gre ac uk emerg images solde. r 20paste 20particles jpg, Solder paste Packing of solder pastes jar and syringe. O Krammer Stencil manufacturing and design 2 44,REFLOW SOLDERING TECHNOLOGY. The reflow soldering technology basically,consists of three steps.
1 deposition of the solder paste,by dispensing topic 1 2. or by stencil printing,2 placement of the components. pick place collect place,3 remelting the solder alloy in the solder paste. usually in an oven,Surface mounted resistor,O Krammer Stencil manufacturing and design 3 44. REFLOW SOLDERING TECHNOLOGY,The reflow soldering technology basically.

O Krammer Stencil manufacturing and design 9 44,BUILD UP OF STENCILS TERMS. The stencil foil is tensioned and fixed to the frame by a metal mesh. The tension of stencil foil is around 50 N cm,Aluminium frame. Metal mesh,stainless steel,Stencil foil,stainless steel. Alignment mark,fiducial mark stencil,O Krammer Stencil manufacturing and design 10 44. STENCIL MANUFACTURING,TECHNOLOGIES, The main stencil manufacturing technologies are chemical etching laser.
cutting electroforming, Stencils are mainly characterized by the quality of the aperture wall the. roughness of the wall,O Krammer Stencil manufacturing and design 11 44. CHEMICAL ETCHED STENCILS, Subtractive technology low price 40 EUR the price is determined by the. size of the stencil foil, Hour glass shape aperture material brass or bronze. Appropriate for pitch size 0 63 mm,O Krammer Stencil manufacturing and design 12 44.
STEPS OF CHEMICAL ETCHING, Chemically cleaned Photo sensitive coating Developing solved. surface applied to top and bottom photo resist, Rinsing off photo Etching of metal Complete etched. resist product,O Krammer Stencil manufacturing and design 13 44. CROSS SECTION OF CHEMICAL,ETCHED STENCIL APERTURES. Single side etching high Double side etching hour,degree of undercutting glass cross section.
Single side etching,Misalignment of phototools,formation of knife edge. between the two sides,O Krammer Stencil manufacturing and design 14 44. LASERCUT STENCILS, Subtractive technology the price is determined by the amount of apertures. Trapezoidal aperture,Material nickel or stainless steel.
