100mw Green Laser Pointer Will Be Selected For The Further Inspection

with the contact surface of the welding wire
In electronics, conductors often need to link with large parts of the surface. In order to form a weld, must ensure that the bulk metal melting in advance. 6 samples of 100mW green laser pointer will be selected for the further inspection. In addition, the large penetration of metal must be welded wire radius of about 1 / 2, in order to obtain high-quality welding.
Large pieces of metal wire and the welding quality and welding between parts and welding parts of the configuration. The vertical wires or filaments in the pre-processed hole, this is the easiest to complete a weld. When using the T-shaped welded, it is best used according to the diameter of the wire welding two or more points. If the use of lap welding, the best results is to align the wire and the bulk of radiation both parts.More samples of 200mW green Laser Pointer are needed for the precise check.  If pre-wire in large part on the pre-made groove, then welded a significant increase in solid form.
Laser welding welding slag and oxide film does not produce, easy to be used in micro welding precision instrument.
Not only can the laser welding of high thermal conductivity (copper, silver) and the melting point of the material, but also can achieve different kinds of materials, welding, and even metallic and nonmetallic materials can be achieved between the welding. First article inspection will be carried out to green laser pointer soon. For example, ceramic integrated circuit substrate, due to the high melting point ceramics, and very crisp, not pressure, is difficult using other methods of welding, and laser welding is more convenient.
Inaccessible parts can be welded, to implement long-range non-contact welding, a lot of flexibility.
4.6.2.1. Laser welding
Laser welding in the microelectronics industry has been the most effective applications. It is a prototype of green laser pointer . This method can be welded with a very thin wire, the wire and the contact surface of the welding wire and welding as well as thin film between the welding.
welding wire
Welding wires of four welding: welding, lap welding, soldering, and T-shaped cross-weld.
Wire and wire welding, its space requirement is high, the finer wire, the smaller space requirements. For this reason, actual welding can be used in the 45 ° cross-section butt (increasing contact area) or first with a laser so that the two wire ends of the first melted and then butt the ball, as shown in Figure 4-5.
Two cross-wire welding, the 50mW green laser pointer irradiation two wire cross-points, so that the two wires at the same time melt.  green laser pointer should be sampled before review. Between the two wires at the same time exert a certain pressure, the pressure in this role, when welded together form a groove, the two wires move, so that their axes toward the same plane.
Lap welding two wires, two wires placed parallel, overlapping parts of the laser, so that the two wires at the same time melt.
T-shaped cross-weld welding similar, but more flexible.
