pcb drilling Aluminum Sheet Entry backup board 

 
     pcb drilling Aluminum Sheet Entry backup board  made from a special aluminium alloy. with a hard temper and made for the PCB industry.
 
     Aluminum Sheetentry boards used as an entry board. for the printed circuit board industry. It is a material produced for PCBs, with a clean, flat. and hard surface that satisfies every demanding application.
 
     For micro hole diameter PCB drilling processes.  it is very important to have good control over hole position accuracy. The Drill Aluminum Sheet Entry Board’s aluminum sheet assists the drill bit to maintain. its position during the drilling process. By minimizing deviations in the drill bit’s position.  the Drill Aluminum Sheet Entry Board helps increase drilling process capability cpk.
 
      When an ordinary aluminum sheet used for high speed drilling processes. the drill bit will slide on the surface of the aluminum sheet. this increases the likelihood for broken drill bits. and decreases drilling precision.
 
-Reduced Drill Temperature - resin layer reduces drill temperature, minimizing drill wear and thus minimizing heat related hole defects.
 
-Improved Hole Wall Quality - the lubrication of the drill, provided by the unique resin layer, 
 
-reduces hole wall roughness and extends drill life.
 
      Aluminum Sheet Backup Board. is the most commonly used in PCB,its advantages including uniformity material. high density and fine hardness. Compare to the paper. and the wood backup board ,it can improve the hole processing quality and remove burr on the surface. Especially for drilling copper foil circuitry board (>17.5mm) . It will more uniformity and not so easy to destroy aiquille when it is small hole drilling .

-Environmental friendly.
 
-Smooth and flat surface with no impurities and low warpage.
 
-Uniform thickness throughout a single sheet and follow the market standards.
 
-No smear or burr occurrence while drilling.
 
-Appropriate surface hardness to ensure no wearing out. or shortening of drill bits' lifetime.
 
We have computerised controlled sawing machines and automatic sealing & packaging machines to. provide a customised cut-to-size service for our customers.
 

aluminum board application 

 
Suitable for general application of PCB board.
 
Suitable for small holes of prexise PCB board.
 
The material used as both an entry and a backing board. during the drilling process in the manufacturing of PCBs.
 
Thinner PH-boards used for routing and drilling, thicker PH-boards used for back-up boards.
 
it is for For double sides, multilayer, FR-4, Teflon, PI, Tg, Rich copper PCB manufacturing.
 
The material used for the most demanding drilling process. in the manufacturing of PCBs.
 
Due to the high temperature resistance of the resin. and the special hard melamine foil materi
 
al it provides an accurate drill entry and even at the highest drill speeds. and smallest holes, drills will not damaged.
 

buy aluminum drill entry sheet tips

 
       the quality buy aluminum drill entry sheet. inner core is HDF it uses special melamine ,resin ,with superior hardness 80 +-5HD . straight, not curved. Flat, hard surface provides the minimization of burring. Due to good hole quality, when drilled. the inner wall -of the hall is less contaminated and suitable for -precise drill. Due to minimizing Burr and Smear, good in soft and -hard board. * reducing the drill bit wear out .

       Many backup board distributors are . misleading customers with lower priced softer wood lower hardness and density. As professional manufacturer , export to many well-known brand name in this industry. we suggest you checking our samples. and compare them with other vendors 'sample of the hardness, density & burring minimization. formaldehyde to ensure what you buy is worthwhile
