Premium pcb assembly manufacturer? Most of our engineer and operators has more than ten years of experience in PCB industry, so we can produce special such as 20 OZ heavy copper board, 4 layers MCPCB, etc. At the same time, we purchased many advanced, art-of-state machines & devices for PCB manufacturing, checking, to improve the quality of our boards. Find extra info at pcb manufacturer. 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. Art-of-state Technology: Most of our engineer and operators has more than ten years of experience in PCB industry, so we can produce special such as 20 OZ heavy copper board, 4 layer MCPCB, etc.

Tg means Glass Transition Temperature. As flammability of printed circuit board (PCB) is V-0 (UL 94-V0), so if the temperature exceeds designated Tg value, the board will changed from glassy state to rubbery state and then the function of PCB will be affected. If working temperature of your product is higher than normal (130-140C), then have to use High Tg PCB material which is > 170C. and popular PCB high value are 170C, 175C, and 180C. Normally the FR4 circuit board Tg value should be at least 10-20C higher than working temperature of product. If you 130TG board, working temperature will be lower than 110C; if use 170 high TG board, then maximum working temperature should be lower than 150C.

When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have been manufactured into the actual substrate of the board, it is more correctly referred to as printed wiring board (PWB) or etched wiring board. Use of the term PWB or printed wiring board although more accurate and distinct from what would be known as a true printed circuit board, has generally fallen by the wayside for many people as the distinction between circuit and wiring has become blurred.

According to different manufacturing method, current there’re three basic types for ceramic board: A) Thick Film Ceramic Board Thick Film Ceramic PCB: Using this technology, the thickness of conductor layer exceeds 10 micron, more thick than spurting technology. The conductor is silver or gold palladium, and was printed on ceramic substrate. More for Thick Film Ceramic PCB. B) DCB Ceramic Board DCB (Direct Copper Bonded) technology denotes a special process in which the copper foil and the core (Al2O3 or ALN), on one or both sides, are directly bonded under appropriate high temperature and pressure.

Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.

If your car starts making strange popping or backfiring noises, it’s time to get your battery checked out. It happens because of fuel accumulation in the cylinders, resulting from a dying battery’s random sparks. The backfiring is the by-product of the sudden ignition of this built-up fuel. Several issues can trigger the backfiring problem, and a failing battery is one of them. Clicking sound when you turn the key If you hear a clicking noise when you turn your key in the ignition, it means that your starter motor is trying to draw power from a weak battery. The clicking sound happens when the battery cannot send adequate power to the starter solenoid. If this happens, you’re not going anywhere until you get a jump start or replace your battery.

Top roofing service and advices in Crawley? There is another part of a roof inspection that many people do not think about and that is the inspection of gutters and downspouts. If your gutters are clogged with leaves, moss or any other type of debris, then this can cause problems. This can cause rain water and moisture to collect and over time the standing water can cause parts of the roof to start to deteriorate. We will also inspect the metal flashings that seal off chimneys or skylights to make sure there is no water damage and that they are installed correctly. We will also inspect all of the collars and boots around all plumbing and other types of pipes. A roof leak can be of huge concern to homeowners.

While concrete roofing tiles are a fairly durable roofing option, the underlayment is not. On average, your concrete roofing tiles will last up to 50 years, while the underlayment will only last about 20 years. This means you will have to go through replacing this layer every-so-often, which adds to the maintenance and cost of concrete tile roofing. The process of replacing the underlayment of your roof can also be rather tedious and time-consuming and keep you from working on other projects in and around your home.

It can be tough to find a floor solution that stands the test of time whole being chemical, spills and stain resistant. Almost every type of flooring has some disadvantage or the other.

An excellent choice for a variety of needs, epoxy floors seem to have fewer drawbacks and more benefits.

Avoid spending large amounts of money on misguided works that actually reduce the property’s value. Kerb appeal is obviously fundamental when it comes to attracting buyers, so doing anything that messes up an older building’s appearance, no matter how well-intentioned, can be counter-productive. The prime example of this is artificial stone cladding glued to the walls, which apart from looking dire has a tendency over time to start cracking with bits dropping off, blocking windows and air vents. Widening and enlarging window openings can create an instant ‘character transplant’, and putting plastic fascias and windows into period buildings is one of the quickest ways of losing money by slashing their market value.

Refamiliarize yourself with what is and is not covered (and for how long) when it comes to your roof. It can help you feel confident when you need to call in the pros.

Our 50-year, non-prorated, transferable warranty is one of the best in the business, guaranteeing you peace of mind season after season.

Interior check: Making sure your attic’s ventilation is up to standard can also be a good way to keep your roof strong and durable. You can also check your roof’s status by checking the panels for any cracks, damage, or deterioration. This will give you a pretty fair idea of whether it’s time for a renewal or patch up for your roof. Minimize walking: Try not to walk too much on your roof. Usually walking on a roof when the shingles are soft or brittle, depending on the weather (i.e. summer or winter), can cause the shingles to deteriorate sooner or get damaged. Find a time in the day when the weather is mild. Your roof is the piece of your house that keeps everything safe and secure. It is the one thing that should be the strongest and sturdiest and, contrary to most belief, looking after your roof to ensure it remains that way is a responsibility that shouldn’t be taken lightly.

Due to the limitation of plant area, or the variety of goods produced.Turning machine has become an indispensable part of automatic production.But there are four problems with conventional turning conveyor. First is time of assembly. Conventional turning conveyor have complicated structure, need two workers use at least 5 hours to replace the PU belt. It need take too much time for assembly. And will waste high downtime cost. Second is maintenance cost. Conventional turning conveyor with many parts and complex structure incurs never-ending costs of replacement parts,labor and downtime. Third is hygiene & safety. The falling of worn and broken parts,lubricant infiltration etc, cold cause food pollution and safety issue. Fourth is service life. Unscientific type of drive makes PU belt stress state uneveness, which would directly shorten belt service life.

Dough mixing machine section is mainly used for mix the material from the dosing system, especially for the sponge and dough process.All ingredients must be uniformly and evenly incorporated in a consistent mass and transformed into a dough which can be processed by the next set of machines. Normally two kinds of biscuit corresponding two types of biscuit dough mixer, horizontal mixer for soft biscuit, vertical mixer for hard biscuit.

Some special hard dough biscuit needs to be sheeted without lamination such as potato crisp cracker. This kind of biscuit needs to use three roller sheeter and gauge roll to reduce the dough sheet gradually. Then dough sheet will be cut in any shape as customer want by using a rotary cutter. This can effectively prevent the biscuit bubble during baking. Biscuit backing oven section is mainly used for baking the biscuit. All kinds of biscuit need to go through this process. There are three main changes which we will see as all biscuit are baked.They are the development of the biscuit structure and texture, the reduction in the moisture content and the development of colour.
