| All of our stencils are 100% laser-cut type 304 full-hard stainless steel, ensuring the finest quality finish on the market today.Stencils are manufactured using a .001″ laser beam with 98% overlap which creates an extremely smooth hole that provides the best paste release.You can choose a prototype “DESKTOP®” stencil, a frameless foil stencil, or a rigid permanently mounted stencil. Both the frameless and framed stencils come in various sizes to accommodate your printer and stencil requirements.
If you need pricing or order information please contact your sales representative. Stencils can be ordered at the same time as your PCBs and will ship prior to your PCB order to avoid any delays. |

All SMT stencils from Bay Area Circuits feature the following:Proprietary Permafid® process creates permanent, non-removable, and non-fading fiducials.

| Fixed Frame Stencils | ||
 |
||
|
Traditional fixed frame stencils are no problem. Bay Area Circuits standard fixed frame stencils are anything but standard. These permanently bonded stencils utilize an exclusive border treatment that combined with our epoxy process, creates a bond that will not fail, never leaving you, or your plate, hanging. Bay Area Circuits stocks all rigid sizes and has complete frame fabrication capability so you are never left waiting. |

| ProFrame®II | ||
 |
||
|
The ProFrame®II is a rigid frame designed to hold interchangeable stencils. Stencils are locked in place and ready for use in minutes. Just like our standard fixed frame stencils, ProFrame®II gives you superior registration, precise, reliable on or off contact printing, longer stencil life, consistent repeatability, and improved yields. Once you are operating with ProFrame®II, your subsequent stencil orders will be filled with ProPlate®II stencils. Since they are shipped without a frame, ProPlate®II stencils are less expensive to produce, ship, and store. Even if your stencil requirements are modest, you could save thousands of dollars each year with the ProFrame®II system. |

| QTS Wizard 20×20 Frame System | ||
 |
||
|
The Wizard Frame System consists of two frames and a stencil. The first frame is a plastic Container Frame which protects against injuries during handling of the stencil’s sharp edges. The stencil is firmly held in the molded plastic Contain Frame (available in green for lead free). The second frame, The Wizard, is a durable, lightweight aluminum stretch frame, designed to mate with the plastic Container Frame. The Wizard frame pneumatically tensions equally on all four sides. |

Why would I need a stencil? tencils are used for even deposition of solder paste onto a bare circuit board. Stencils replace hand soldering of surface mount devices, and the inconsistencies created by hand soldering. |
||
How do I choose my stencil thickness? The stencil thickness is determined by the smallest component land pattern. If you are not sure, our design staff can choose the optimum thickness based on the data you supply. |
||
What are home base apertures and why would I need them? Home base apertures are used to control solder balling and tomb-stoning of chip components. |
||
What are Trapezoidal Apertures and why would I need them? Trapezoidal Apertures are created by distorting the beam on the laser, creating a draft in the aperture wall. Trapezoidal Apertures are effective if you plan on a long dwell time between printing of solder paste and placement of components. The taper in the aperture wall causes the paste to sit on top of itself, rather than sliding out the sides. |
||
What are fiducials? Do I need them on my stencil? Fiducials are alignment marks. If your screen printer is equipped with a vision system, fiducials half cut in the stencil to allow for the printer to automatically align the board with the stencil. If you are manually aligning the stencil with the board, you could either full cut the fiducials or just use the surface mount pads. |
