C-TPAT on-site audit certification. 

 
Science  and  technology  are  the  primary  productive  forces,  with  over  years  of  hardworking, 
Dinghua  has  owned  core  technology  of  temperature  controlled  and  38  patents  and  finished  the 
development  and  production  of  manual,  semi-auto  and  automatic  series  and  realized  the  second 
revolution  from  traditional  hardware  combination  to  integrated  control.Our  p

roducts  have  been 

exported  to  Europe  ,  America,  Southeast  Asia,  Australia,  Africa,  the  Middle  East,  Taiwan  and 
more  than  80  countries  and  regions  and  established  the  relatively  sales  network  and  terminal 
services  system.We  are 

becoming  the  pioneer  and  guide  of  SMT  welding  industrial  and  our 

products  have  been  applied  in  individual  maintenance,industrial  and  mining  enterprises,teaching 
and  research  work,military  manufacturing  industry  and  aerospace industry  and  so  on,  which  has 
treed good reputation among users. 
 
We believe:your successes are our successes,let‟s work together and build a 
better future!

( 一 )

Installation sites 

In  order  to  ensure  that  the  useful  life  of  BGA  rework  station,  installation  of  repair  station  must 

meet the following conditions: 

1

Away from flammable and explosive materials                                     

2

Do not splash water or other liquids 

3

Well-ventilated , dry place                         

4

Stable , flat areas less susceptible to vibration 

5

Place less dust                               

6

Prohibit Placing heavy objects on top of the control box 

7

Without the affect of air-conditioners,heaters and fans 

8

Reserved for 30cm to move and rotate around the upper for the back of rework station 

 

(

)Power Requirements
