Abstract: Microbial leaching was used to mobilize copper from two kinds of waste electronic scraps used as raw materials for printed wire boards.
The content of the most important materials remaining is: plastics 19%, bromine 4%, glass and ceramics 49% [2].
Methods and materials Source of electronic scraps.
The scraps of TFCCL, used as the raw materials used for producing PWBs of electronic products, were obtained from Kunshan Jinda Corporation, Jiangsu province, China.
The scraps of TFCCL with green non-conductive coating, which are used as raw material for producing PWBs of cell phone, were obtained from Shanghai Weimei Corporation of Science and Technology, China.

The Positron Annihilation Lifetime (PAL) technique provides information about electron densities and the Doppler broadening of annihilation radiation (DBAR) measurement gives only qualitative information about the momentum density for materials under study [1, 2].
The PAL spectra in materials typically exhibit three lifetime components.
The �\ decreases with increasing the frequency verifying the fact that, for polar materials (PVC), the initial value of �\ is high but as the frequency of the a.c. field is raised, the value of �\ begins to drop.
This is not the bulk dielectric constant but rather is due to the free charge motion within the materials and is sometimes known as “space-charge polarization” [6].

Introduction In the last decade, normal ferroelectric such as lead zirconate titanate [PbZr1−xTixO3, PZT] has become an important commercially produced piezoelectric materials.[1-3] Excellent piezoelectric properties of PZT have been observed in compositions close to the morphotropic phase boundary(MPB Zr:Ti ,52:48). [1-3] Locating the MPB for the ferroelectric materials is very important for making the phase diagram and for obtaining excellent electrical properties.

Remarkable differences were observed in the Doppler-broadening of the positron annihilation �-rays in these materials, which reflect the different densities distribution of the momentum for electrons annihilated with positrons.
On the other hand, after the discovery of C60 and C70 fullerenes, positron annihilation lifetime was also examined for those materials[1, 2, 3].� In a previous report, we reported our first measurement of� the positron lifetime and Doppler-broadening of the annihilation � ray[4].� At that time, although we measured the Doppler-broadening of the annihilation � -ray using just a single Ge detector, we were able to observe a difference in the Dopplerbroadening spectrum of C60, C70, nanotubes and graphite.
To clarify those differences, we tried to examine those materials using the coincidence Doppler-broadening method.
This would reflect the different positron distributions in those materials caused by their geometric structure.

A MEVVA implanter can easily produce high densities of various metallic ions, and therefore is proper equipment for surface modification of various materials.

However, the processing time of press forming is extremely short, thus the contact between the die and the material varies with time; making the flow of the material extremely complex.
