Generally, there areB/C/D/k/IAnd other models, as shown in the following figure:
Commonly used Hakko welding stations and nozzles, such as 900m-t-k, 900m-t-3c, and 900m-t-2.4d.
How to choose a suitable soldering head
I,Select proper soldering head size and shape: 1. selecting an appropriate soldering head can make the work faster. 2. selecting an appr
foreign body under the feeding device, and the spring is aging, or poor electrical), resulting in insufficient or poor retrieval of materials and throwing materials, there is damage to the feeding device. Countermeasure: Adjust the feeding device, clean the feeding platform, and replace the bad parts or feeding device. When there is a throwing phenomenon, you can first ask the on-site personnel to describe it, then, we can find out the problem based on the observation and analysis, so that we c

Blur tool, sharpen tool, smudge tool: RUse of the Blur tool: Reduce the contrast between pixels and reduce the contrast of the image.The sharpening tool, in contrast to the use of the Blur tool, enhances the contrast between pixels and enhances the image's contrasts.Smudge tool: the equivalent of a finger wet and applied in the image, drag the pixels of the smear to the specified place, the property bar can modify its brush's smudge intensityDodge, deepen, s
Sponge Tool: Can remove the saturation in the image or increase the saturation of the image. In the mode of the option bar there is a color-adding two patterns, through which the image can be adjusted to reduce the stiffness of the image, of course, we can understand it as a deepened version of the Dodge. Add and remove colors in the new Photoshop version to reduce saturation and saturation of two mode options, but the actual use is the same.

The tutorial teaches you to use Photoshop to make 3D stereo hot soldering iron text effect, the main use of a sunset material to stack the effect of fire, like the students hurry to learn it!

1. First open the material picture, select all pictures (Ctrl + a) or use the Marquee tool (m) as needed to select a part of the picture, copy (Ctrl + C). Set the foreground and background
In our daily life, we often see sponge Packing Box absorbent. Why? There are many small gaps in the sponge packing box, which are filled with air. when the pressure is pressed to absorb water, the sponge is pressed to discharge its own air. when the pressure is lifted, the original shape will be restored and the original air will be inhaled. On the one hand, the
PS Sponge tool How to use?
Sponge tools can increase or decrease the color saturation of the image, is used in PS software to absorb the color of the tool. Use this tool to turn colored parts into black and white.
Unlike the Dodge tool, the Dodge tool cuts all colors, including black, to a white at the end of the Dodge. The sponge tool only sucks to remove co
Blur: The limit comparison is reduced.
Sharpen: Add a dot.
Smudge: Pixel offset.
Deepening: increased saturation and reduced brightness. Exposure refers to intensity. The range generally selects the middle tune. Add a shadow.
Dodge: decrease saturation and increase brightness. Exposure refers to intensity. The range generally selects the middle tune. Add highlights.
Sponge: Does not change the high light and dark tone, increase or decrease the sa

PCB Optimization Design (i.)2011-04-25 11:55:36| Category: PCB design SMT technology is now very mature and widely used in electronic products, therefore, electronic product designers need to understand the SMT technology common Sense and manufacturability design (DFM) requirements. SMT process products, at the beginning of the design should be integrated into consideration of the production process, raw material selection, equipment requirements, device layout, test conditions and other element
planting.The use of small tin planting board is to fix the IC under the tin planting board, scrape the tin paste and then blow the board together, compress the ball and then remove the IC. It has the advantage of tin planting Board during hot air blowingBasically no deformation, if there is a lack of feet or the tin ball is too small after a tin planting phenomenon can be secondary treatment, especially suitable for new users. I usually use this tin board. The method we will introduce below is
Wave automatic soldering technology has been used in the electronics industry for many years, but the late failure of solder joints is still a headache, which greatly affects the quality and reputation of electronic products.This paper intends to make a preliminary study and discussion on the basis of practical experience.The so-called "late failure of solder joints", refers to the surface appears to be the quality of the solder, there is no "lap weld

Prepare tools for welding the integrated circuit of the table, such as a good soldering iron (the finer the head, the better) and solder paste. For fine pin spacing, first apply a layer of solder paste on the clean pad, and then use a clean constant temperature soldering iron to thin a layer of Solder Pad (according to observatio

the plug-in, mounting holes, slots, v-cut and other high stress concentration areas, reduce cracking or cracks.(11) To consider whether the socket, connectors and other components between interference, and structural design is contradictory.(12) The same type of cartridge components in the X or Y direction should be placed in one direction. Polarity-mounted components of the same type as far as possible in the X or Y direction consistent, easy to produce and inspection, the same board can be up
