Double Sided FPC Green Oil PCB, Green Oil Print Circuit Board, Double Sided Flexible PCB with High Quality Fabrication Manufacturing and Supplier.
At the first sight, you will see that there is a layer of green oil on the PCB. It is called solder mask which is comprised of resin, talc and pigment. Of course, solder mask also has other colors, including red, yellow, black and so on, but green is the one that used the most widely.
High quality PCB with green solder mask
Generally speaking, the circuit board refers to rigid PCB. The surface treatment process and solder mask of rigid PCB use green, red or yellow oil, that is, the so-called green oil board, red oil board and yellow board.

Flexible green oil solder mask circuit board
Jinghongyi PCB, engaged in pcb prototype and small and medium-sized batch production and manufacturing has nearly 10 years of experience. If you are looking for your PCB manufacturer, we are your best choice. Extended reading 1. There PCB is required to go through the exposure room with yellow light in some processes of fabrication and the visual effective in exposure room is better than the solder mask with other colors. What`s more, the PCB needs to coat tin, SMT and AOI testing during SMT soldering. All of these processes require optical position alignment and the green solder mask is better for the recognition of instruments. 2. Before the flying probe testing is applied widely, most of the wires on the PCB are relied on the naked eyes to inspect.It is very tired to detect the boards in strong light. If the rigid board is green, it will not do a lot harms to eyes. 3. There are cobalt and carbon in blue and black solder mask,which have a certain conductivity, so there is a risk of short circuit. However, the PCB with green oil will be more friendly to the environment. Because it will not release poisonous gases when use the printed circuit board in a high temperature environment. 4. Since some famous brands began to use black solder mask in 2007, such as ASUS and Micro-Star and then people kept an eye on the colors of PCB.In this way, people gradually believe that PCBs with black solder mask means that the boards have high quality.After that, more and more PCB manufacturers started to apply black solder mask. NO one said that printed circuit boards with black solder mask are better than those with green solder mask.It is entirely due to the misleading caused by the famous brands using black solder mask to identify product positioning. 5. There is no reason, just because of habit, so it has been used all the time. JingHongYi PCB is the premier expert in PCB manufacture of electronics, brings a unique combination of technology and quality that offers a competitive supply of printed circuit board and PCBA. With high qualified engineers, we are able to help you find a PCB with high quality.

Advanced Features for Flexible PCB
As the flex circuit market continues to expand, there have been many advances in technology including: Heat Sinks – Heat sinks can be laminated to flex circuits to dissipate heat away from sensitive components such as LEDs. Component Assembly –We offer through hole and surface mount capabilities, as well as in circuit testing, conformal coating, and electrostatic protective packaging. Controlled Impedance – With increasing signal switching speeds, engineers need to understand and control the impedance of traces. With short signal transition times and high clock rates of modern digital circuitry, traces need to be considered transmission lines instead of simple interconnections. With today`s higher speed requirements, controlled impedance traces are designed to minimize electrical reflections and ensure an error free transition between the track and interconnections. If perfectly optimized, controlled impedance allows control of the physical dimensions and material of the cable. Controlled impedance signal transmission requires flexible circuit materials to be uniform in both thickness and electrical properties. At Flexible Circuit Technologies, we have extensive experience in designing and manufacturing flex circuits with controlled impedance. Crimp Pins – Crimp Pins are mechanically attached a circuit to allow for soldered connections. Graphic Overlays – Graphic Overlays can be placed over flexible circuits, rigid boards or membrane switches. The overlays provide the user interface with the underlying circuit and typically are used in conjunction with LEDs, LCD displays or dome switches mounted on thie circuits. The overlays are made from polycarbonate, polyester or acrylic materials. Laser Skived Slots and Holes – Historically, X-acto knives or razor blades were utilized to cut intricate areas of a flex circuit, the successful yield of which depended on the skill of the operator. FCT has dramatically improved this process by utilizing a top-of-the-line laser beam with extremely precise depth control to accurately cut the underlying substrate of a flex circuit. Precise laser beams can skive circuit openings with the utmost precision. Overmolding – Overmolding is the process by which FCT embeds electronics versus simply placing electronics on the circuit. As electronic devices and required interconnections become more compact, embedding electronic circuitry within the cable assembly is a cost effective alternative to on-board electronics. Most often referred to as smart cables or dongles, these embedded devices can solve many packaging challenges. Panelization – During the panelization process a stiffener is applied to the boundaries of multiple circuits on a panel so that they can be easily processed through the [pick & place" and wave soldering processes. Once the panel of circuit boards is done, simply clip them out and they are ready to go. Pressure Sensitive Adhesives (PSAs) – PSAs with a release liner are used in applications where a portion(s) of the circuit needs to be secured to a specific location within the final product. During assembly, the release liner is peeled away and the exposed adhesive allows the assembler to press the circuit into place and keep it there. Sculptured Flex Circuits – Sculptured flex circuits are special in that the copper conductors vary in depth and thickness in different places. The copper is thin at the most flexible part of the circuit and thick at the interconnection point. Sculptured flex circuits allow for bare metal connections (like a plug in) and remain strong at the solder joint formation. Sculptured fingers provide a more reliable alternative to mechanically fastened crimp pins. Shielding – Shielding is applied when an application requires limits in electromagnetic and/or electrostatic interference. Protective shielding can be patterned or solid. Either way, it reduces noise and controls impedance of signal lines. Stiffeners – Stiffeners are applied to flex circuits where additional support is needed such as areas of component assembly or underneath exposed traces that will be plugged in for connection. Common stiffeners are FR4 and polyimide. Wire Assembly – In certain applications a combination of flex or rigid circuit with traditional wire may be a more economical design that still meets the needs of the customer`s subassembly. At Flexible Circuit Technologies, we have the capabilities to design, source, manufacture and assemble the entire subassembly incorporating the circuit, wiring and components. This level of capabilities and commitment is what differentiates us from other flex circuit suppliers. Flexible Heaters – Flexible heaters are thin, bendable heating elements, shaped to fit your unique heating equipment needs. Hot Bar Solder – Hot bar solder connection is a way to eliminate a connector set between the hardboard and the flex circuit. This connection provides an efficient, durable and less expensive alternative to a standard connector set.
