An unbelievably simple approach to order from us.
Just two steps from you
Step #1: You- Send Gerbers with quantity, specifications, destination, etc. View details
Step #3: You- Confirm your order and pay. View payment term
All in advance (preferred, it will save bank charges)
30% deposit and balance before delivery against pcb reports and photos of bare pcb, packages and packing list (OK). View reports and photos format
Step #4: We- PCB layout check and fabrication. View engineering query format
Step #5: We- Reports of fabrication status. View fabrication reports format
Step #6: We- Deliver and send you delivery note. View delivery note format
11.You don’t specify the color of legend, we would like to use white, pls confirm it .
Our suggestion :color white
12.this board you demand the base copper 0.5oz and finish copper 48UM that we have difficult to build ,we will follow the reply of p/n”55555” which use base copper 0.5Oz and finished copper thickness min 38um to build , pls confirm
13.This board you demand the GOLD thickness 1um and NI thickness 5um that we have difficult to build ,we suggest to follow the standard of IPC-6012 class2(gold min 0.8um over Ni min 2um),pls confirm!
14.there is no surface treatment requirement in your order and specification , could we decide the surface treatment is hot air solder leveled (HASL) ?
our suggestion: HASL
15.can we regard “pcb code ”as part number of ended customer such as “pll1”?if not ,please give us more detail!
16.we can’t catch the meanings of “refusal’s logo” clearly , pls explain it to us
17.see the picture 1),these legend are too small to print and no space to enlarge ,we will modify similar character as picture 2), pls confirm！if (picture 2) is not ok ,pls modify it and offer the modified GERBER file to us , tks!
Our suggestion : agree modify similar character as picture 2
18.we have no the standard of “IPC-7351”on hand , and we don’t know if there are some useful information in it .
Our suggestion: 1) Ignore it 2) we will follow IPC-A-600G instead of IPC-7351 .
19.customer require TG≥180 degree ,and use SY1170 material ,but we would like to tell you, for SY1170 material , their TG only to be 170 degree ,detail see attachment , they are conflicted with your requirement
suggestion : use SY1170 material with TG≥170 degree
20.See Q3,the customer require overall PCB thickness max 1.0mm,and you require core thickness is 0.70mm,if you use 0.70mm core ,the board thickness is only to be 0.80mm,if you hope to the max thickness to be 1.0mm,so we think that your thickness follow 0.90+/-0.10mm,we can use 0.80mm core.
Our suggestion: The board thickness is 0.90+/-0.10mm.
