FAQ about Sayfu:
How long have your company in this field?
We are JiangMen OEM plant on PCB(printed circuit board) fabrication with experience over 15 שנים.
Why Choose us?
Sayfu is forced up to the mount as a good choice as your partner for PWB making , you can get
• Industry’s Best ON-TIME Shipping Record
• Expedites a specialty…even Same Day & Weekend Turns
• Standard Spec orders shipped on time – or FREE!
What is your Lead time?
Lead time is usually punctual here, for some special situation, we can also advise customer in advance to avoid any inexpectation or loss at customer side. Please check our lead time table, which shows you not only for quick turn prototype but also for mass production for printed wiring board .
What is your testing policy and how you controle the quality?
For circuit sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step. For multilayer board, we will do 100% AOI checking while around 80% for double sided circuits.
What is your certificates?
ISO9001, ISO14001, UL, RoHS report. We can provide the report of raw material, including CCL, solder mask etc based on customer’s requirement.
What is your package?
With Inner vacuum package and out carton.
How is PCB shipped?
This is depend on customer, sometimes we ship through our forwarder, who is also the agency of DHL, TNT, UPS, Fedex, and so on. Our forwarder can provide too much better freight cost than we get directly from those express enterprise. If you have your own forwarder, it will be more than welcome.
What is your producing ability?
Our ability is average 30,000 square meters per month for PTH boards, while 10,000sqm for FPC and rigid-fleible circuits.
I only have the pcb sample, not pcb file, can you produce it for me?
כן, we can copy file based on your sample, and will create the PCB gerber data, and the production is based on the very gerber file.
Can you design gerber file ( PCB layout ) ?
כן. We are focus on PCB layout and PCB design.
What kind of PCB file format can you accept for production? What CAM software do you use?
We accept Gerber file for production. CAM350, GENESIS, UCAM, GC-CAM, V-2000.
Will you allow me to put several pwb part number together into one panel?
כן, this is usually happen in our factory, this way can help customers reduce some cost and to a certain degree, it can help reduce some pcb assembly cost too.
What CCL brand you use for your PCB(printed wiring board)?
Shengyi, ITEQ,KB, SL, NANYA, TACONIC, ROGERS,ISOLA and so on.
What is your minimum order quantity?
We have no limitation on MOQ, prototype, medium volume and large volume are all acceptable.
Will RoHS Lead-Free Custom Spec. Boards be marked with lead-free symbol?
כן, but need customer to specify this requirement in file.
Are my design files safe when I submit them to you for board manufacturing in China?
Any customer’s file will be protected very well here in we factory and not let any third party know. We can sign NDA with you.
Which year was Sayfu set up?
Guang Dong Sayfu Multilayer Circuit Co.,Ltd was set up in the year 2001 in Shenzhen, חרסינה.
PCB Fabrication in SAYFU PCB we focus on multilayer rigid pcb, High Density Interconnect pcb, Heavy copper board, High Frequency pcb/RF PCB & Ceramic PCB & Rogers PCB & Teflon PCB factory in China, now we can help customer do PCB assembly, Board assembly and DIP assembly services.
Around 500 full time staff with a capacity of 40ksqm per month, 50,000 square meter of factory
Kindly advise if any further info required and we will be happy to assist.
For price testing and try our service, you can send us your gerber file, we will quote to you right away.
