Top pcb assembly supplier? Best Technology, establish on June 28, 2006, is a Hong Kong registered company whom focused on one-stop solution provider of FPC, Rigid-flex, MCPCB, FR4 PCB, Ceramic PCB, Special PCB such as Heavy Copper (up to 20 OZ), extra thin PCB (0.10, 0.15mm), and PCB assembly service. Find even more details on printed circuit board manufacturers. The layer on top of the copper foil is called the soldermask layer. This layer gives the PCB its green (or, at PCB & MCPCB, red) color. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers. In the example below, the green solder mask is applied to the majority of the PCB, covering up the small traces but leaving the silver rings and SMD pads exposed so they can be soldered to. Soldermask is most commonly green in color but nearly any color is possible. We use red for almost all the PCB & MCPCB boards, white for the IOIO board, and purple for the Best Technology boards.
A single sided flexible printed circuit (1 layer flex circuit) is a flex circuit with one layer of copper trace on one substrate, and with one layer Polyimide coverlay laminated to copper trace so that only one side copper will be exposed, so that it only allowing access to copper trace from one side, comparing to dual access flex circuit which allows access from both top and bottom side of flex circuit. As there’s only one layer of copper trace, so it also named as 1 layer flexible printed circuit, or 1 layer flexible circuit, or even 1 layer FPC, or 1L FPC. The multi layer flex circuit refer to a flex circuit with more than 2 layer circuit layers. Three or more flexible conductive layers with flexible insulating layers between each one, which are interconnected by way of metallized hole through the vias/holes and plating to form a conductive path between the different layers, and external are polyimide insulating layers. Quality Policy: PCB Quality is the core of products. All of engineer & vital department guys has more than five years expenrience in PCB industry, we follow up the default PCB standard, as well as with clients’ special request.
Flat Flexible Cable (FFC) is made of PET insulation material and extremely thin tinned flat copper wire, it has free bending and folding, thin thickness, small size, simple connection, easy to solve electromagnetic shielding (EMI). Common ffc cables’ specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm and other various pitches to match different types of connectors. Rigid-flex PCB is a circuit board combined of rigid board and flexible circuit, from 2 layer to 50 layers, has the advantage of rigidness, flatness, flexibility and bendability. You can see advantage of rigid flex circuit such as design high density, less components need, less space, and stack up. Welcome to visit Best Technology rigid flex pcb manufacturers.
While Flexible PCBs offer significant advantages, they are also prone to damages. Broadly damages can accrue from two factors: environmental factors and problems that account for issues at the design/fabrication stages. Let us look at both these aspects in some detail. Several environmental factors can cause damage to PCBs, including moisture, static electricity, dust, extreme temperatures, chemical corrosion, and pests. For example, if the PCB is stored in an environment with a lot of moisture, it can destroy the flexible PCB. Moisture can result in a short. Also, given that molds can grow in a damp environment, it will result in a circuit failure. The storage area must be free of any static creating agents. Storing PCBs in carpeted rooms, for example, can result in damage to printed circuit boards on account of the static electricity generated.
Best Technology wholesale fr4 pcb manufacturer specialized in many kinds of fr4 board and provides fr4 pcb assembly service since 2006. Please contact Best Technology fr4 board suppliers anytime and get quotes! FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). After add copper layer on one or each side FR4, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal printed cricuit board (PCB). Printed circuit board using FR4 as core material will be named as “FR4 PCB”. Wholesale fr4 pcb board is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on. Find extra details on bstpcb.com.
Generally speaking, aluminum is the most economic option considering thermal conductivity, rigidness, and cost. Therefore, the base/core material of normal Metal Core PCB are made of aluminum. In our company, if not special request, or notes, the metal core refer will be aluminum, then MCPCB will means Aluminum Core PCB. If you need Copper Core PCB, Steel Core PCB, or Stainless steel core PCB, you should add special notes in drawing.
