Something you need to know In silkscreen printing, people want customized colors. Color mixing is an important step. The basic principles of it are the subtractive color principle of colorants and the additive color theory of colored light. To get the correct color, ink mixing should be done under stable natural light,...

Back adhesives are ready to be torn off and used. They are easy to assemble, carry and disassemble. They are thin and light, have good adhesion and good temperature resistance. Pasting steps of back adhesive 1. Make sure the surface to be attached is flat, rust-free, oil-free, and dust-free. If necessary, use petroleum...

There are two ways to make prototype for membrane switch. 1. Soft proofing Soft proofing is done on color monitor. It is undoubtedly the most convenient and efficient way. It requires the color monitor to have high precision and be properly calibrated. There are some obvious shortcomings. Low resolutionon comes first. ...

Acrylic sheets should be stored flat. Put products of the same size together to a stack, or put smaller ones on top and larger ones on the bottom. If long-term storage is required, the stacking height should not exceed 500mm. Here are some other tips for transporting and storing acrylic sheets. 1. Moisture resistance A...

Flexible Printed Circuit (FPC) is something that is widely applied in electronic equipment. Due to its flexibility, thinness and bendability, it is increasingly favored by electronics manufacturers. To ensure the normal running and extend the service life of FPC, regular maintenance is required. Here are some suggestio...

Capacitive touch technology has become the mainstream of touch technology. The buttons can improve the overall appearance of products. Even 20mm of insulating material shell (glass, plastic, etc.) is not a problem for sensing. The device can accurately detect effective finger touches, ensuring that the product's se...

1. Tactile feedback Membrane switches can be divided into two types: tactile feedback and non-tactile feedback. There are two kinds of structures for non-tactile types: flat and embossed buttons. Non-tactile membrane switches do not have any requirements on handfeel, but they require high sensitivity. They can be turne...

Membrane switches are customized products. If you don't know much about them, it's easy to buy low-quality products. Now, let's talk about how to quickly customize membrane switches. 1. Confirm the specifications and materials The first thing is to confirm the specifications of the membrane switch, such as ...

1. Introduction Flexible printed circuit (FPC) is used for connecting electronic components. It has the advantages of being light, thin, soft, high in bending, stretch-resistant, and stable in signals. It is widely used in automotive electronics, smart homes, and consumer electronics, etc. FPC board is made of polyimid...

Conductive paste The conductive carriers in the conductive carbon paste are graphite and carbon black. Carbon black is a non-metallic conductor. It is difficult to combine with oxygen and other things in the air, thus effectively ensuring the reliability and durability of the membrane switch. Graphite has smaller frict...

Surface roughness 1. Testing principle There are always uneven surfaces on graphic overlays. Use the stylus (or probe) of the instrument to test the surface roughness Ra. 2. Test instruments and supplies a. Testing instruments that meet the testing range and accuracy requirements are available. The instrument error is ...

1. Visual inspection We judge based on material properties. Here is an acrylic sheet. We can check the color or the gloss. If anything is wrong, the acrylic sheet is not good. 2. Burning test Burn a small piece of acrylic. We identify the quality through the smell. The burning speed also shows something. If the acrylic...
