JINHUA SMT Workshop Production Line:
JINHUA DIP Workshop Production Line:
We have years of experience and stable relationships with authorized electronic components manufacturers and distributors, we can make purchase in full accordance with the customer's designated supplier. Can also help customers reviwe and improve the supply chain, identify the specifications of electronic components, lower the cost and avoid the introduction of any defective products. All parts go through 100 percent quality inspection before use, so you always get real, quality parts.
Q1. What service do you have?
We can offer you PCB Design, PCB board manufacturing, Components or Parts Source, Surface Mount (SMT), Thru-Hole (THT),hybrid of both, Functional Test, Wire Soldering etc. one stop PCB&PCBA service.
JINHUA Technology is a one-stop PCB and PCBA factory with over 13 years’ experiences.
Q3. What is needed for quotation?
Gerber file and Technic requirements (material, surface finish treatment, copper thickness, board thickness, and so on.)
Q4. What file formats do you accept for production?
Gerber Files+BOM File+Centroid File(other names maybe: aka Insertion, Pick-N-Place, or XY Data)
Gerber Files: including files: copper (track), soldermask, silkscreen, solder paste, drill, outline files
Q5. Do you assemble BGA? Any special requirement on this?
Yes, we have the ability to handle BGA of 0.25mm pitch with X-ray testing. For BGAs, there are two designs with via on pad and via near pad connected by shorter trace. We need to tent and fill any vias near pad of the BGAs with solder mask to ensure the soldering quality. But for vias on pad, we need to fill via with resin to make sure good soldering quality.
Q6. How do you handle the excessive and unused parts?
Excessive parts do exist because we will ask for some percentage of overage for consigned/kitted orders, or we will buy more for the same purpose for those Turn-key orders. You can either ask us to ship back to you these unused parts together with the loaded boards, or keep them in our shelf for your next order. All up to you.
Q7. What is your testing policy and how you control the quality?
As to PCBA production, there are automated optical inspection (AOI) for each batch, X-ray inspection for BGA parts, first article inspection(FAI) before mass production.
Normally 24 hours to 48 hours as soon as receive internal engineer evaluate confirmation.
There is no MOQ in Jinhua Technology. We can offer prototype, expedite prototype, small& medium amount, big amount pcba service.
