33、We will mill, cut, mold solder, program, and draw our way to evaluating product design.
34、At this stage, it's easy to remake a solder connection if there is a problem.
35、Is the viscosity of the solder mask after preparation checked to ensure the quality?
36、The causes for defects from the point of wetting force for the flux activity of solder paste were studied, the solder paste according to the wetting force was selected.
37、The experiment is conducted by selective laser heating and melting the thin solder layer and then preprinting it on CCL in order to form the matrix with solder pads.
38、The stainless tubing is less likely to kink than copper but it is harder to solder without an acid treatment.
39、In addition, the solder mask coating on printed circuit board, with the plasma treatment, can also obtain certain roughness and high active surface, thus improving the solder coating adhesion.
40、Effects of isothermal aging and joint size on the strength of Sn-3.0Ag-0.5Cu microscale solder joints
41、The head of electric iron is heated to the melting point of welding solder, which is immersed with an even layer of solder and clean the head with clean, wet sponge or wet cloth.
42、After being unsealed, the solder pastes should be completely used under a room temperature within 24 hours.
43、Soldering flux meeting the lead-free requirements is used for the lead-containing solder paste manufactured by our company.
44、Process modifications such as solder pot finishes for wave soldering equipment to avoid leaching issues are now available.
45、The factors affecting soldering ability of rosin-based flux for lead-free solder paste, and the factors affecting erosion resistance are discussed.
46、The execution of the liquid photoimageable solder mask of the printed circuit board was briefly introduced. The process and its quality control were also illuminated.
47、A semiconductor package substrate for preventing deformation mainly comprises a flexible dielectric layer, a plurality of pins, at least one reinforced metal pattern and a solder mask layer.
48、The text on the solder mask layer is overlapping the text that on the circuit layer. We suggest move it away. Please refer to Q7.
49、You could just as easily use two button cells but it is not advisable to solder to these types of cells.
50、The result shows that the plastic strain at the heel region induced by wire bonding process, molding process and the thermal stress and strain in solder reflow are the main causes of heel crack.
51、The permanent safe radiator selects the high-quality low carbon steel for use, use the advanced arc solder technology of argon and advanced static surface spraying craft , thus make quality and appearance of the products ensured.
52、Pall very spacious, may tune, rock NIE Inscribed on the corner of the open-life memoirs, it was introduced, the memoirs of a total of more than 2,600 characters, all with iron solder stonemason the current time.
53、From low cost, straight solder and press-fit terminations to high reliability connectors qualified to MIL-C-24308, many styles and options are available for light duty industrial applications.
54、The injection stream welding plant comprises a clamp, a soldering flux generator, a preheater, a solder groove with a first-level spout, a voltage-stabilizing filter and a nozzle;
55、There are problems in the fact detection on the X ray 2 D projection of weld seam, which the cracks along the projection direction and the concave holes on the surface of weld seam may be recognized as the air holes and the thin area facts(the cracks and nonpenetrate solder) may not be detected.
