Stencils are jigs used to print solder cream onto circuit boards.
It is designed to manually print solder onto the circuit through the hole opened on the stainless steel.
We use Laser Cutting, Chemical Etching and Additive Manufacturing.Following the development of machines, we too are required for higher quality stencils.
At Nakayama Riken, we make the best highly precision and functional stencils by carefully discussing with our clients
We use high quality YAG laser. It allows clear cutting and is possible to use with any material. List of Product
Using high exposure and developed chemical etching, it is possible to open multiple holes at once and available to manufacture any type and size of stencils.Using high exposure and developed chemical etching, it is possible to open multiple holes at once and available to manufacture any type and size of stencils. Characteristic list
The opening is made with electroforming made by nickel.It is applicable for fine openings and multiple thickness. List
Smoothing out the edges of the SUS plate after cutting out the holes will smoothing the solder printing. Thus ease mounting parts on QFP/BGA the size below 0.4mm or on 0603 chip. More details
By usung a special method to coat both sides of SUS plate(backing), it will improve the soldier printing quality and reduplication of printing.
By combining with electropolishing it could be applied on 0402 chips.
More details
Half etching could make different thickness of holes to control the amount of soldier past on a certain part. Furthermore, if parts are loaded on the circuit, by half eching the back of the stencil it could avoid the parts and improve the printing quality. However, there are limits of usage so please contact us for more details.
