Melamine backup baord VS phenolic wood backup board for pcb drilling

 

Melamine backup baord

 
     White Melamine Backup Board is a kind of new type of drilling cushion for small hole.
     
      Then it turn to be compound board with solidity surface and stretchy midst core.
 
      It can used for the hole on precise multilayer circuit board. designed to replace the phenolic backup board in particular. especially for the pinhole aperture, multilayer board and flexible Board.
 
-the surface hardness is the same as the phenolic backup board. but stabilize dimension and not easy to distort.
 
-easy to treat with after using and accord with environmental protection standard.

melamine coated backup board Features

 
      Disposal backing board is free of phenolic resin and formaldehyde. backup board is non-toxic to mammals and fish. backing board is biodegradable. It may burned, subject to local legislation, thus providing heat energy.
 
Thickness:2.5mm,2.7mm
 
Size:37*49,41*49,43*49
 
      The series include wood fiber backup board. wood fiber Back up board, White Melamine Backup Board. HDF, MDF Backup Board
 
Thickness tolerance: ± 0.10mm
 
Width tolerance: ± 3.30mm
 
Length tolerance: ± 3.80mm
 
Diagonal tolerance: ± 5.00mm
 

white melamine backup board Advantages:

 
excellent underlay board no chipping. and free burr properties means lower risk of flute blocking and drill breakage
 
• Reduced friction causes less wear on drill cutting edges, improving drill quality
 
• Reduced drill burr due to a smooth, hard and very thin overlay
 
• No phenolic or resin content to contaminate holes
 
• Excellent flatness and tight thickness tolerances
 
• Suitable for all drill hole size
 
• Usable on both sides without loss of quality. because of symmetrical build-up unique to 
 

melamine laminated backup board Application

 
      White melamine backup board used in the drilling hole of PCB /FPC .
 
       WOOD Backing board. for high speed circuit board PCB drilling machine and 2.0mm wood backing board. designed for automatic PCB DRILING machine. recommended for cnc printed circuit board drill of high-tech micro printed circuit boards. multilayers and flex-rigid boards. 
 

phenolic wood backup board

 
      Phenolic Drill Exit Board material has tight thickness and flatness tolerances. Itcontain no abrasives that could increase drill wear. or contaminatesthat could evacuated through the drilled hole. The surface is smoothand hard to suppress exit burrs
       
       An important drilling consumable is the underlay or backing material. The purpose of the backing material is to prevent exit copper burrs. on the underside of the drilled boards. and to provide adequate space fordrill stroke termination. An acceptable backup material does not contaminate the hole and helps cool the drill bit. thereby improving hole quality.Phenolic Board material has tight thickness and flatness tolerances. Itcontain no abrasives that could increase drill wear or contaminatesthat could evacuated. through the drilled hole. The surface is smoothand hard to suppress exit burrs
 
      it's more enconomical than that of drill aluminium
 

phenolic backup board Features

 
Thickness: 1.5 / 2.0/ 2.5mm
 
Tolerance of thickness: ± 0.15mm
 
Warping degree: ≤0.6%

Melamine backup baord VS phenolic wood backup board for pcb drilling, Which is better ?

 
      melamine backup board is a kind of new type drilling cushion for small hole. It can used for the pinhole on precise multi-layer circuit board. Especially for the pinhole aperture, multilayer board and flexible board. Its designed to replace the phenolic backup board in particular. the surface hardness is the same as the phenolic backup board. but stabilize dimension and not easy to distort. Easy to treat with after using and accord with environmental protection standard.
 
      compare to Phenolic Back up Boards. melamine wood backup board:
 
It's a composition of the Melamine paper and wooden fiber board with high density. It's especially made  to replace the Phenolic backup board.
 
It's difficult to distort. The warping degree is smaller than the Phenolic backup board.
 
It reduces the abrasion of the drill and lengthens the life of drill.
 
It can save the cost and it has more sizes.
 
It doesn't pollute the environment.
 
It can used for the hole on precise multi-layer board and flexible board.
