| Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean socks and this system sounds pretty good to us. I'm contacting the manufacturer but would like to hear your professional opinion. | | Thanks, | Joe | Laser Cut SMT stencils with Re-usable ACCUFRAME
PNC Inc. is a quality manufacturer of LASER CUT SMT STENCILS. To make laser cut stencils affordable, PNC Inc. has developed a unique Re-Usable frame called " ACCUFRAME � " (Patent Pending). By eliminating the secondary mounting process of the conventional stencil, a laser cut stencil can now be priced competitively with chem-etch technology. What is ACCUFRAME�"? The concept behind ACCUFRAME� is that it is Re-Usable with equal foil tension on all sides. ACCUFRAME � is designed to quickly load and unload your stencil foil off line in a very short time frame. ADVANTAGES OF ACCUFRAME � 1. Storage space (no wasted floor space with conventional mounted frame) 2. Shipping costs (we ship only the foil, no added weight from the frame) 3. Eliminates debonding (no mesh) 4. Supplied to our customers at no charge. 5. Adjustable foil tension PNC loans these frames to every one of our customers. We loan as many "ACCUFRAME �" as required for your production. We also assume full responsibility to service them at no cost to you. In case, any of the "ACCUFRAME �" becomes unusable, a replacement is sent to you immediately.
Frame Sizes 12x17 Bolt Pattern (1/4-20@30.00 & 18.00 on center). 20x20 Bolt Pattern (1/4-20 @ 21.00 & 18.00 sq. on center).
Cleaning process No different than conventional stencils

No chemicals � Environmentally friendly process. 6. Drastic reduction in print rejects 7. Clean and exact printing image of the solder paste 8. Fine-pitch screen <= 250�M can be released without problems
Quality Overview? We at PNC strive for excellence in quality. Our laser stencil fabrication process has minimal routing sequences that reduce manufacturing errors. Such errors as mesh stretching, mesh adhesion to frame, gluing foil to mesh, mounting foil upside down, mesh emulsions and chemical etch tolerances are now taken out of the formula. With all of the secondary processes eliminated, we can now direct more time and energy towards engineering and customer service.
Frequently Asked Questions Q. How do we store the foils? A. There are 4 methods for storage. a. We can provide a job organizer envelope which is reinforced to protect the foil from damage. These organizers also have side pockets for job related paper work. You can slide the organizer into your existing stencil rack. If need be, you may slide multiple organizers into one stencil slot to reduce your storage. b. PNC can also supply giant vertical filing cabinets. You can file foil sizes up to 25" x 38". c. We also can supply our customers with horizontal filing cabinets. These slim-line steel cabinets can store foils up to 47" x 36". d. Another popular method is to hang the foils. Each stencil foil will hang by itself in its own transparent bag. The storage units come in two styles, wall mount or stand-alone. Q. How do you price laser cut stencils? A. We have a flat fee pricing schedule. We feel we can expedite our stencils to the customer's benefit using this method of pricing. Q. Do I have to purchase ACCUFRAME from PNC ? A. No, PNC will loan ACCUFRAME free of charge to our customer with the first stencil order. After first order, PNC will ship only foil to you. We will loan you more than one frame if you necessary.
