PCB Manufacturing demands preparation of design well in advance. The finalized designs are fed into the systems and the production is carried away. If the boards are of small sizes, multiple boards are made on a single large board and separated into

Hi Mike, I appreciate your views, but how does this relate to the original question? Roger asked "Wash how? Wash How often? amd PM? He didn't ask who. It seems that your response in a "yellow page" ad and not an answer to the question. At least Bi

Encoder is a kind of measuring device, which mainly converts pulse signal into data signal for people to read. Users choose different types of encoders with different application values. Besides, when using the encoder, people need to pay more attention to the wiring to ensure the normal measurement of the equipment.

There is an increase in the number of optical sensors and cameras being integrated into electronics devices. These go beyond cell phone cameras into automotive sensors, wearables, and other smart devices. The applications can be lens bonding, waveguide imprinting, or other applications where the adhesive is in the optical pathway. To support these various optical applications, new materials with tailorable optical properties are required. There is often a mismatched refractive index between plastic lenses such as PC (Poly Carbonate), COP (Cyclo Olefin Polymer), COC (Cyclo Olefin Copolymer), PMMA (Poly Methyl Methacrylate), and UV curable liquid adhesive. A UV curable liquid adhesive is needed where you can alter the refractive index from 1.470 to 1.730, and maintain high optical performance as yellowness index, haze, and transmittance. This wide range of refractive index possibilities provides optimized optical design. Using particular plastic lens must consider how chemical attack is occurring during the process. Another consideration is that before the UV curable liquid adhesive is cured, chemical raw component can attack the plastic lens which then cracks and delaminates. We will also show engineering and reliability data which defined root cause and provided how optical performance is maintained under different reliability conditions.
