Someone has ever asked sunny : does "Mier" has a English translation ? Sunny replied to the man without a second thought , "Mier is translated from it's pronunciation of Chinese “弥迩” ,which means in English "two partner in cooperation make business go fast .
There is a very interesting story about Mier when it was built by Sunny . Sunny was graduated from school in 2008 and worked on PCB manufacturing since then .
During 5 years work , she modified many kinds of gerber file including through hole pcb , HDI , and acknowledgeable in the process of PCB manufacturing .
When sunny built her website , she post the manufacturing process chart in order to make designer learn more about the manufacturing and help them layout the gerber .
Many customer has ever inquired sunny " If I want to get holes size 0.8mm ,how can I design the hole size in the gerber file regarding the copper thickness of the hole wall " It was a question that was asked by thousands of times during sunny's work in the company .
This is a question associated with the pcb manufacturing . Before the factory drill the hole and going to plate the hole , they will enlarge the hole to 0.95mm , ie 0.15mm more for plating , thus is makes sure the final hole size 0.8mm +/-0.15mm .
There is another question weight sunny a lot about the drills , it's the format . many of the green designer sent sunny the drill file in Rs-274x format , because the file with extension .txt , but they failed to understand the format which should be in Excellon .
Here is the difference between the .txt file in Excellon format and Rs-274x ,
Generally , drill size and drill coordinate should be compromised in the .txt file , then that is Excellon format which can be used for PCB manufacturing . please note : There shouldn't be "*" in the .txt file ,that is the signal of drill file in Rs-274x format .
Excellon format
So much things for Sunny to share with .
Last year , Sunny left the company that she worked for 2 years and start to setup a company for garment , because her mother make clothe for more than 20 years . It seems that sunny will be appears from PCB area , however , not .
Everyone don't appears as long as she has a good story to tell . Many of customer that she fulfilled try to find sunny , because of her specialize in PCB designer and production , and always assist with them in design and others . Finally , sunny forward to PCB company .
Her company got many support from her old customer at initial time . As a provider of PCB ,PCB assemble , FPC ,HDI for R&D member , she setup fast service (24h & 48h ) and flexible price , by this way customer can get PCB fast and reduce the wast on the area of pcb and save some cost . So , by now , her company is popular among her customers .
To make the one who is new to PCB design more understand the pcb manufacturing , sunny post a video in her website , though is was coppy online , it is enough to help designer learn .Later ,Sunny will update the video to new .
The website "smiery" is compromised of "mier"+"sunny" ,can you understand ?
