Die Attach Tools 

 There are many types of Die attach tools, which can be roughly divided into:
1.Adhesives dispensing series
2.Pick and plcae series
      Among them, LONGYI focuses on the Adhesives dispensing series, and launches a ceramic and stainless steel dispensing needle, which is different from general metal products on the market.      
 

   The  ceramic dispensing needle main features:

  • It can solve the rough inner diameter and make the glue flow more stable.
  • Rockwell hardness is HRA80-90, second only to diamond. Much more than the abrasion resistance of metals.
  • Easy to clean the inner surface

Precision measurement

LONGYI uses X-Ray’s measuring equipment inspection to ensure the quality of shipment! Reverse engineering service is also proposed without damaging the workpiece!

  • From the rigorous structural analysis, the bottom of the ceramic nozzle has a sealing tube connected to the vacuum pump. During operation, the air in the nozzle is pumped through the sealing tube, so that the nozzle is firmly attached to the surface of the article device, thereby carrying the article or transfer.

When the ceramic glue needle is glued at a speed of 90%
When the tungsten steel needle output speed is 90%
When the tungsten steel needle output speed is 90%
When the tungsten steel needle output speed is 50%
When the tungsten steel needle output speed is 50%

When the painting speed is 90%, the tungsten steel pen shows an uneven amount of glue, making the product easy to NG.

Seeing the illustration, the painting speed of the tungsten steel needle must be reduced by 50% or adjusted to a lower speed to achieve the same glue volume and uniformity with the ceramic glue pen at 90% high-speed painting.

It also raises the number of output and reduces concerns about downtime maintenance.
