chips themselves must be as thin as possible
The goals are to reduce memory cost, and make the populated PCB even thinner. Combining more memory capacity with even thinner PCB QUICK WASHboards after mounting the memory chips means that the chips themselves must be as thin as possible. For standard PCB development, the thinner the chip is, the more USB connectordifficult it is to handle, which usually means a rise in manufacturing cost. However, if the memory can be embedded into the PCB, it becomeshand dryer possible to achieve a thinner main board even without machining centermaking the memory chips unduly thin. This could only be achieved by usingthe expertise of Samsung’s memory arm.SEMCO claims that developing and manufacturing passive components in-house also contributes to improved competitiveness for its device embedded PCBs. A source at R&Sthe firm explained "We make our own passive components, meaning it is a lot easier to design them specifically for use in device embedded PCBs."The use of specially RF PCBdesigned components also improves device embedded PCB reliability. Few Japanese board manufacturers make their own passives, and since the components weren't optimized for embedding in boards, there have been mounting reliability problems such as poor connection reliability. It is thought that this type of problem is less likely to occur with SEMCO's device embedded PCBs.

be supplying product to Samsung Electronics
Printed circuit boards (PCB) with passives, integrated circuits (IC) and other components embedded USB connectorinside resin boards are intended to boost mounting density. At the 39th Japan Electronics Packaging and PCB QUICK WASHCircuits Association (JPCA) Show 2009, held at the Tokyo Big Sight exhibition sight in June 2009, R&Sa number of firms displayed device embedded PCBs with diverse components including everything from chip-type passives and film capacitors to wafer-level chip-scale packageshand dryer (CSP), bare chips and light emitting diodes (LED).One of the booths attracting the most attention was that of Samsung RF PCBElectro-Mechanics Co, Ltd (SEMCO) of Korea (Fig 1). The firm has been developing device embedded PCBs machining centerfor some time, but finally began volume production in the first quarter of 2009. In addition, the firm appears to be supplying product to Samsung Electronics Co, Ltd of Korea for use in what is expected to be huge volumes of mobile telephones.

device embedded PCBs supplied by Japanese manufacturers
Depending on what SEMCO does, it is quite possible that the device embedded PCB market―until now almost completely PCB QUICK WASHmonopolized by Japanese manufacturers―could change dramatically. Until now, Japanese manufacturers have pretty much ignored SEMCO and other overseas device embedded PCB USB connectormanufacturers, with the attitude that "anyone can show a prototype at a show."If device embedded PCBs from SEMCO are actually used in mobile phones from Samsung Electronics, though, the hand dryersituation will be a bit different. The Japanese machining centermobile phone market has actively utilized device embedded PCBs supplied by Japanese manufacturers, R&Sbut that market is less than 40 million handsets a year.On the other hand, annual mobile phone shipments by Samsung Electronics, at a tad under two hundred million units, RF PCBare significantly higher. The second Samsung Electronics begins full-scale use of SEMCO's device embedded PCBs, it seems pretty clear that SEMCO will suddenly cast a big shadow in the industry.One of SEMCO's strengths is the combined capabilities of the Samsung group. Samsung's mobile phone division which the end user is aware of, is only part of it. Examples of other key parts are the group's memory arm, the firm handling passive components, and integrated development.Part of this is evident in the structure of the device embedded handset PCBs shipping from SEMCO. They are supplied with the memory already embedded in the main board.

said it has received additional orders
March Plasma USB connectorSystems (Concord, Calif.) said it has received additional orders for its Provia plasma system for printed circuit PCB QUICK WASHboard (PCB) manufacturing, and will ship the tools to PCB hand dryermanufacturing R&Scustomers in both Asia and Europe over the next several months.system is used primarily for RF PCBblind via and through-hole desmear and etch-back steps, which are critical for manufacturing machining centerhigh-quality circuit boards. Without proper desmear and etch-back, the subsequent metal plating steps will not be successful, leading to poor PCB quality, scrap, and re-work costs, the company said.
