1. Accurate optical positioning system
Four way light source is adjustable, light intensity is adjustable, light is uniform, and image acquisition is more perfect; identification (including uneven mark points), suitable for tinning, copper plating,Gold plating, tin spraying, FPC and other types of PCB with different colors.
2. Intelligent squeegee system
Intelligent programmable setting, two independent direct motors driven squeegee, built-in precise pressure control system
3. High efficiency and high adaptability stencil cleaning system
The new wiping system ensures full contact with the stencil ; three cleaning methods of dry, wet and vacuum, and free combination can be selected; soft wear-resistant rubber wiping plate, thorough cleaning, convenient disassembly, and universal length of wiping paper.
4. Printing axis servo drive
The scraper Y axis adopts servo motor drive through screw drive,to improve accuracy grade,operational stability and extend the service life,to provide customers with a good printing control platform.
5. 2D solder paste printing quality inspection and SPC analysis
The 2D function can quickly detect the printing defects such as offset,less tin, missing printing and connecting tin, and the detection points can be increased arbitrarily; SPC software can ensure the printing quality through the sample analysis machine CPK index collected by the machine.
What is solder paste?
Solder paste is a mixture of metal solder powder and flux - the two elements required to successfully solder together two pieces of metal. Much like any other form of solder, such as solder strip or wire, you can get solder paste in different types of alloys including silver and gold. You can also get solder paste that melts at different temperatures (hard, medium, easy). Essentially, solder paste is like any other form of solder you can buy - you just have the added advantage of it being pre-mixed with flux.
1. One of the best things about using a solder paste syringe is the fact that it comes in a syringe! This makes the application of solder paste incredibly precise - excellent for soldering jump rings together. Simply remove the cap from your syringe and secure the needle that comes with it in place.
2. Check that the metal you're soldering is clean and free from any debris or greasy fingerprints. This can interfere with the soldering process making it much more difficult for your solder to flow nicely through the joint.
3. Make sure that the join you're soldering is completely flush. File until you can no longer see any light seeping through the join. This will make sure that your solder joint is as strong as possible and help the solder paste flow nicely through the join.
4.Apply a small amount of solder paste to the solder join or area of metal that is going to be soldered. Apply a little pressure to the syringe plunger - you'll soon get used to the pressure required to apply the tiny amount of solder you need to solder findings.
Wipe away any excess solder paste from the syringe and replace the cap. Get into the habit of doing this immediately after each use to maintain the consistency of your solder paste for longer.
