Achieving fine pattern processing that was not possible with conventional FPC boards!
【Features】 1. Fine patterning with a pitch of 30μm (L&S = 15/15μm) is possible. 2. Depending on specifications, connection bumps can be formed on the pattern or the backside. 3. By combining laser processing and plating technology, through-hole conduction treatment on both sides is possible.
This circuit is output-stable, so even if the input voltage fluctuates (90V⇔110V), the current flowing through the LED remains unchanged.
We are developing a wide variety of inverters for general use, medical use, industrial use, and more on a daily basis. Additionally, it is possible to customize products developed to meet customer requests according to customer specifications.
Compatible with LEDs from Lumilets, Nichia Chemical, and others!
This circuit is output stable, so even if the input voltage fluctuates, the current flowing to the LED remains unchanged. Additionally, the brightness is always constant. It comes with protective circuits such as a current fuse and an oscillation stop safety circuit for overheating prevention, and it includes input and output lead wires attached to the circuit board upon delivery. As it is an inverter, it is compatible with both 50Hz and 60Hz. 【Features】 ■ Brightness is always constant ■ Compatible with 50Hz and 60Hz ■ Insulated type ■ Comes with protective circuits *For more details, please refer to the catalog or feel free to contact us.

Achieving fine pattern processing using methods such as etching and additive techniques!
FPC (Flexible Printed Circuit) boards are circuit boards that use polyimide film as the base material and have copper electrodes patterned on them. Since the base substrate does not use organic materials such as adhesives, it can be used in high-temperature environments. Additionally, Howa Sangyo Co., Ltd. has achieved fine pattern processing that was not possible with conventional FPC boards by using methods such as etching and additive processes. Fine patterning of less than 50μm is possible. Depending on the specifications, connection bumps can be formed on the pattern or the back side. Furthermore, by combining laser processing and plating technology, through-hole conduction treatment on both sides is possible. For more details, please contact us or refer to the catalog.
The brightness is always constant.
This circuit is output stable, so even if the input voltage fluctuates (90V⇔242V), the current flowing through the LED does not change.
Compatible with LED lamp currents up to 700mA!
This product is a constant current board with dimming function suitable for LEDs with a lamp current of up to 700mA. Since this circuit is output stable, the current flowing to the LED does not change even if the input voltage fluctuates. Additionally, the brightness remains constant. It is compatible with both 50Hz and 60Hz due to its inverter design. It includes protection circuits such as a current fuse, an oscillation stop safety circuit for overheating prevention, and a no-load short-circuit protection circuit. 【Features】 ■ Brightness remains constant ■ Equipped with protection circuits ■ Insulated type *For more details, please refer to the catalog or feel free to contact us.

Current adjustment is possible using the dimming volume located on the board. In addition to this board, we offer various other constant current boards. Please feel free to contact us. 【Features】 ■ Compatible with LUMILEDS LEDs ■ Current adjustment available *For more details, please refer to the catalog or feel free to contact us.
A meticulous support system from circuit and pattern design to prototyping and mass production within Japan.
We will propose a design based on mass production manufacturing at overseas partner factories, aiming for total cost reduction. Our experienced designers, who are well-versed in electrical characteristics such as digital/analog circuits, impedance, and crosstalk, will provide optimal circuit design using simulations and other methods. Our manufacturing technicians, stationed at each overseas partner factory, will directly manage the manufacturing process and quality, and we will also achieve low-cost supply through strengthened management of production and inspection processes.
