The E.P.A. projected three possible paths for PCB's in the Hudson: yellow is no action, red is controlling leaks at the old G.E. plant sites, green is with dredging. G.E. contended that the red line was the best option but the E.P.A. in 2002 settled on scooping out the tainted mud to speed things along.

What are the benefits of PCB REwork Stencil? Please visit: www.soldertools.net/pages/-StikNPeel%E2%84%A2-Rework-Sten...
The benefits of the StikNPeel™ stencil over the mini metal rework stencils are enumerated in this brochure. The most striking benefit is the adhesive backing of the stencil. This overcomes the lack of being assured co-planarity between the stencil and the PCB. Please watch the video.

Nowadays, the reduction of the size of the basic printed circuit board will reach half or the quarter of the original size. The extremely thin wires that designers couldn't use before are now the mainstream, and the thinnest wire with 75 micrometers (3 mils) has gradually been reduced to 30 micrometers (1.2 mils) or even thinner.
Manufacturers of a sophisticated microcircuit can be divided into four groups. The first group is in the Asian area, which has developed the unique thin wire process for phones or iPods and can arrange wires of 40-50 micrometers. The second group consists of the research and development companies of limited numbers which produce small numbers of very professional circuits with thin wires of less than 40 micrometers.
The third group is expanding its business of large and medium-sized PCB with the highest speed. They provide a little output with wires of 75-40 micrometers in width, and they can produce several thousand within weeks. At last, the fourth group produce PCB normally with the wires of 125-75 micrometers and includes a large number of manufacturers and participants.
As the microelectronics business expands, more and more PCB companies find out the necessary technology in producing the very thin wires with a width of 40 micrometers, and even less than it, circuit designers need to be familiar with the new design rules and the merits and demerits of microelectronics manufacturing.

4 Layer HDI PCB with 0.38mm pitch BGA
0.4mm pitch BGA circuit board is a bit difficult to do ,but we can make 0.4mm CSP, even,0.38mm CSP PCB ,we can make now.
0.4mm pitch BGA, means the space from BGA ball to another BGA ball is 0.4mm. This PCB is very small,10*10mm, and blind vias from L1-L2,it is 4 layer PCB ,0.6mm, half-hole plating.min hole 0.15mm,via in pad, 0.38mm pitch BGA. All the above features, we can see from below image.
Actually,we tried to made with board with standard blind PCB technology,but it is too difficult due to all difficult features put together.At last,we have to make this PCB with HDI technology and drill the blind vias with laser.that is very perfect.
Such HDI PCB with only 0.38mm pitch BGA,the via in pad is required.We can make such HDI boards in 8-10 days. To Know More Information Click:- www.stormpcb.com/
