PCB Market Europe And The United States

,

Europe and the United States is weak, weak consumer demand for electronic products, the impact of the traditional PCB season, look forward to the second half of the year, Apple new models innovation, coupled with major brands to steal the end of the season, will continue to pour soft board, carrier board and HDI board needs ; Therefore, the overall PCB industry in the second half of the year, “eat soft do not eat hard”, soft board, load mills and revenue is expected to continue to grow up.

Hand-held intelligent products with strong demand for flat-panel computers, printed circuit board (PCB) manufacturers are exposed, especially HDI, soft board and other manufacturers in August reported better news. (2367) also has a history of the next high level, the performance is quite bright, legal person said that due to the end of the major companies will be the first to be ahead of the first quarter of the year, The introduction of new models to seize the business opportunities, and because of smart phones, tablet computers are widely used HDI, soft board and other products, the group is expected to remain bright in the second half of the results.

In the second quarter in the PCB manufacturers, the most outstanding performance of the soft board, revenue growth of about 15-20% over the previous quarter, as the carrier board is affected by the impact of the earthquake, the quarterly increase of about 6 to 7% (8046) benefited from the CPU carrier board to improve the yield, mobile phone customer orders increased, driven by the CPU carrier board and packaging board growth, but also drive the gross margin back to temperature; but the other side of the hard board factory Jian Ding (3044) by the PC, TV sales as expected, the impact of photovoltaic panels and other product lines, the overall performance of PCB hard board factory as soft board.

(6269) EPS to 2.79 yuan to win, a record high record, Jia Lianyi (6153) after-tax net profit of 591 million yuan to earn the most, while the Asahi Soft (3390) consolidated gross margin up to 30.56% ranking first, but the other side Yi Jia (2402) due to output efficiency and poor yield under the drag, the loss of the dilemma, the first half of the loss of 0.69 yuan per share after tax.

In fact, the soft board industry has been oversupply in the past, so there speculative competition, but since last year, thanks to smart phones and other commodity demand warming, performance gradually shine this year, become the PCB industry, the most watched ethnic groups, even the (8213) in order to expand the product line, also decided to enter the main ring (3267), as Taiwan Table Branch (6278) also continued to invest with the Thai.

Legal users said that not only Apple new products continue, the United States Intel (Intel) introduced Ultrabook laptop to become 3C market, is also the focus of the second half, Intel can sell and become a tool against the iPad, but also Taiwan’s soft board, HDI board In the next year’s performance focus.

Quick Detection Of PCB Board Failure Problem Method

Quick detection of PCB board failure problem method

PCB board is not a simple process to do the board, drill holes on the components like. PCB production is not difficult, it is difficult to produce after the completion of the troubleshooting. Whether it is personal enthusiasts or industry engineers, PCB circuit board in the debugging when the problem is quite a headache, like the programmer encountered BUG the same.

Some people have a strong interest in debugging PCB circuit board, as programmers in the solution of BUG, common PCB circuit board problems and many common problems in addition to circuit board design, electronic components damage, short circuit, components The quality of PCB circuit board disconnection failure a few.

Common PCB circuit board failure is mainly concentrated in the components above, like capacitors, resistors, inductors, diodes, transistors, FET, etc., integrated chip with crystal clear damage, and determine the components of the more intuitive method of failure Eyes to observe. There are obvious damage to the surface of electronic components have a more obvious signs of burning. Like this type of failure, directly to the replacement of the new components can be resolved.

Of course, not all of the damage to electronic components can be observed with the naked eye, such as the above-mentioned resistance, capacitance, transistor, etc., in some cases damage can not be seen from the surface, need to use professional inspection tools for maintenance , Commonly used with the inspection: multimeter, capacitance table, etc., in the detection of an electronic component voltage or current is not within the normal range, indicating that the components or a component of the existing problems, direct replacement and then check to see if it is normal.

Components, such as broken, whether it is observed with the eyes or instrument testing, can be detected, but sometimes when we are on the PCB board components, will encounter problems, but the circuit board and can not work Case. Many novice encountered such a problem Mozhe, and can only do a board again, or buy a piece. In fact, encountered this situation, a lot of time in the installation process components, due to the coordination of various components of the work, there may be performance instability.

In this case, the instrument has been unable to help, you can try to determine the current voltage according to the possible range of failure, as far as possible, experienced engineers may be able to quickly determine the fault area, but the specific components which is broken But can not be 100% sure. The only way to try to replace a suspicious component is until you find the problem element. Last year, my notebook motherboard water, in the master when the maintenance also encountered a fault can not detect, and in the maintenance process to replace the three components, namely the power supply chip, diode, USB charging components (that is, notebook blue Jack that, shut down the state can be charged to the device), and finally through a wave detection with the investigation to replace the suspicious chip, only to determine the edge of the South Bridge chip a short circuit.

The above is actually the problem of electronic components, of course, since the PCB circuit board as a foothold of components, then the circuit board failure is certainly there, the simplest example of the death of tin parts, due to the production process, PCB corrosion process, there may be disconnection problems. Encounter this situation, if you can not make up the line, then only use fine copper wire to fly to solve.

PCB circuit board failure is not significantly damaged in the case, check up really very troublesome, and in the investigation process, there will be a focus on the spirit, to be identified after the problem will be inexplicable sense of accomplishment, the programmer to solve BUG is This feeling, I often like to troubleshoot some difficult to repair the board, I think it is a pleasure.

LED Chip Offer Pick Up? Crystal Electricity: Just Stabilized Flat

For foreign investment, Crystal said that the price is not a comprehensive product prices are space, especially in China’s wafer plant continues to open new capacity under the circumstances, because China is the world 90% of LED lighting manufacturing, LED lighting chip prices just no longer crash, showing flat down, but as long as the supply is still greater than the demand, the future is still the possibility of falling; crystal to disperse the product layout to adjust the structure to get rid of the pressure on the price of lighting, this season has been effective.

Foreign investment pointed out that the three blue LED chip prices in May began to rise 10%, and Hua Chan chip prices are also close to the rate of nearly 1 percent, with the crystal power to freeze after the production price is indeed good, the factory is also synchronized Follow-up to raise prices; chip factory price adjustment will help adjust the profits of lighting, crystal power is currently the proportion of Blu-ray revenue is still up to 60-70%, prices will help to operate positive.

“Since the beginning of May, part of the LED chip prices have risen 10%,” the news, according to LEDinside asked Sanan company to get the reply is that they do not have a large price hike. But some of the Chinese chip manufacturers part of the LED chip items have a slight hike, mainly because some of the second-tier packaging manufacturers in order to ensure that the supply, so prefer to use a little higher prices to the market getting goods.

At the same time, LEDinside also confirmed from the relevant person in charge of Hua Can, Hua Chan some varieties of products have price hikes, but also because customers are worried about the tight supply and demand of the market, in order to obtain a more stable supply of chips and take the initiative to raise prices, There is no plan for full price increases
