The SMT industry's products on the number of residual tin beads are certain norms.
So we focused on the study of literature for some of tin beads resulted in a large number of factors and residual principle lie, in Ning-Cheng Lee, the study that caused large tin beads of reasons solder of SMT particle size, Opening plate design, welding pad size and welded to the impact of such factors curve [2].AIM in the literature that caused tin beads is a key element plate opening size and shape of solder of SMT printing parameters, the viscosity solder of SMT back solder of SMT welding curve and particle size and other factors all affect tin beads have a lot of factors [3].
，However, in recent years due to patent protection has expired gradually, coupled with the semi-finished products and technical advances, to meet the high-end technology development, low-cost, component performance and the overall package size of demand, Grain and in particular high I/O, high-frequency demand, Minute crystal technology have become high-end package the best choice [5][6].
Discussion This section is the application of the Taguchi method (Taguchi method) in the Minute crystal system - which is a tin slag residue quality improvement and the best design parameters, the experimental design is the use of impact surface mount technology manufacturing process to design factors, and the system under way after the residue in the passive components on the tin beads number and size as a basis for assessment (Figure 9 below), because too many beads tin residues in flux-cleaning system, is likely to be washed down to the internal chip, making the chip caused the tin-lead Bump short circuit, which will affect product quality.

Researches [3,4] presented a scheduling strategy for real-time tasks with both timing and cache space constraints, which allows each task to use a fixed number of cache partitions.
We propose a finer-grain approach based on lifetime and instruction fetching timing to obtain runtime inter-core interferences.
The status of instruction a1 is still hit. (2) As depicted in Figure 1(b) and W Core1(case2) in Table 1, The number of interferences is 2 and the interfering instruction are changed to c3 for a3 and c5 for a5.
As abovementioned, whether runtime inter-thread interferences occur or not and the total number of runtime inter-thread interferences are all dependent on IFT.
Because we aim to analyze run-time inter-core interferences for inconsecutive concurrent programs, so we construct two inconsecutively running threads based on matmul whose big code size can discourage interferences caused by address mapping. 1) First, in order to evaluate the validation and tightness, we triple the number of loops, named as matmul-3.

The prior austenite grain size given by austenitizing treatment was about ASTM No. 9.
The thermal fatigue properties including the damage factor (crack width × crack depth) and crack density (number of cracks per unit length) were revealed from a polished cross-section investigated using an optical microscope.
This indicates that the damage factor has a clear dependence on the number of cycles, as shown in Fig. 6 (a).
However, the crack density was not strongly dependent on the number of cycles (Fig. 6 (b)).
The damage factor has a clear dependence on the number of cycles.

The number of cycles varied from 100 to 400 cycles.
Specimens were identically maintained as specimens from ordinary concrete C50/60 and were subjected to the same number of cycles.
Fine-grained structure of UHPC in the connection with excellent mechanical properties would resist on a long-term basis to extreme conditions represented undoubtedly by these freezing cycles.
The UHPC specimens UHPC showed even better resistance in pull-out tests after a high number of cycles.
A surface damage due to freezing and thawing cycles was observed at the specimens made from ordinary concrete while the specimens made from UHPC remained without any damage after high number of cycles.

It has been demonstrated that the MPs have some undesirable effects such as the local loss of coating adhesion [14, 15], surface roughening [4, 15, 16], grain coarsening [16], large voided regions [16], surface craters resulting from the detachment of the MPs [3].
The number and size of MPs decreased with the bias.
As can be seen in Fig. 3, the number and sizes of the craters increased with the increase of bias.
At the initial period of the erosion, the number and size of the damage islands varied significantly with the substrate bias at which the coating was deposited (see Fig. 6).
The number and size of the damage islands increased with the increase of the substrate bias voltages above 150V.

For the measurement of tensile fracture strength, the fine- grained Y-TZP was examined in addition to above-mentioned three kinds of materials.
Clearly, the anelastic strain is greatly enhanced in the reduced Ce-TZP, incorporating a large number of oxygen vacancies.
Considering the valence and the amount of each additive dopant, the fully reduced Ce-TZP has larger number of oxygen vacancies than that of 3Y-TZP.
Mg-PSZ also does not relate the effectiveness of anelasticity to the number of oxygen vacancies.
It is noted that the extent of anelasticity cannot be determined only by the number of oxygen vacancies in the matrix.
