 22 Feb 2005 10:50 What do you think about electronic assembly in China? |
|
|
|
I'm from Europe. I'm starting to consider the possibility to find a company that can assemble our PCBs in China (for lower costs).
Anybody has experience on this issue?
What about:
- prices
- lot quantities
- delivery and lead times
- reliablity
- finding the right contacs...
Any information/suggestion/opinion is welcome.

I am in Hong Kong and I was working in an OEM/ODM manufacturer with factory based in shenzhen one year ago.
Price always depends upon the number of components and the complexity of your PCB. Typically, it will count the soldering points of the PCB.
Quantity always not a problem, because china is easy to get some labour to work and sometimes may have OT in case the shipment deadline is tigh.
Delivery and leadtime, it depends:
1. If you do not supply components, the lead time will also count on the purchasing time, usually 3 to 4 weeks for purchasing time.
2. Manufacturing time depends on the traffic of the production line and your product complexity.
3. Delivery... well, usually delivery by ship, sometimes urgent by air.
Reliability, hmm... it is better to have your own QC to check rather than just trust the factory output.
Finding right contacts..... I have one or two, PM me if any want to have their contacts......
Also you can find some OEM/ODM manufacturers in the website: www.globalsources.com
Hope this help.
Added after 3 minutes:
If your PCB are mostly SMT components, many china factories already have SMT placement machines which give a certain degree of automation and fast production with better quality.

Thank you for your help.
Do you think that lots of 250/500 pcs are ok for this kind of business or are too small?
And how to understand if the maufacturer is reliable? Do you think that it is possible to start a good relationship without going personally to China to visit its site and meet people? I think that probably at the beginning the payment is due in advance, so how to avoid sending money and not receiving anything?

250/500 pcs, be honest, a very small quantity.
Usually, each production line has capability at least 2 to 3k per day. Just one or two days may finish your order at this amount.
It is hard to tell manufacturers are reliable or not. It will be better you travel to china and have a look at various factories.
Or you can take a chances of electronics exhibition in hong kong at april or october, and pay visit to these factories at the same time.
Or you can get in touch with some of your local people who already have business with these manufacturers.
For payment, I think mostly using T/T, but I am not sure.

| Agree! Assemble in Europe, at least you can save a lot of transportation fee and have a better control of the quality.

Thank you everybody.
Here there are some companies that are buying components directly from China (even lots of 200-500 pcs) at a so low cost that delivery charges are not relevant.
That's why I was thinking that assembly of PCBs was a feasible solution for that quantities.
It would be interesting to have some real world case histories from european people/companies that tested this kind of business.

Hi to all,
Having looked at more than one product, such as scales , car amplifiers....
I think the internals are very poor.
But maybe this is because of the low cost.
I prefer not to go down in price, and maintain very good quality!!
Bye.

Quality control of china production actually not too bad.
Some suggestions are:
1. You must got your own QC to check the end products.
2. You must only give orders to those with ISO certificates factories
3. Everytime you find a new factory, go there and have a visit before you place your orders. Look through the environment with your own eyes and you will have some ideas on it.
4. If possible, do have a periodic visit to the factory
5. Of course, a very low price may not be a good choice.

You are right, that's why our partners are all big factories, although their price is higher than some small plants.

I have been to suzhou for many times. The companies you mentioned only interested in very big orders. They will omitted all the orders under millions of dollars.

I suggest this: if for any reason (knowledge, previous experience, working there, ....) anybody in this forum directly knows a Chinese manufacturer, please post the name and share your experience.
I think that reference is better than advertising, and the companies involved could appreciate this.

Good idea Andrea. Let me share first: I had worked for a big He Bei provience's manufacturer, whose name is Yuan Dong (means far-east in Chinese, http://www.ydpcb.com) for several years as the manager of department of oversea. They had very good equipment and can provide high quality products. But comparing to some other manufacturers in East or South China, the price is lack of competitive when the quantity is large. But Yuan Dong accept orders at all quantity, but South China manufacturers only accept big orders, or the price is very high for small order. This is why I left Yuan Dong and setup my agency company. I can provide more products and better services for all kinds of customers.
My suggestion is: for small company who commonly place the orders at several hundreds of pcs, Noth China companies is OK. When the quantity reach several thousands, go to east china or South China. Wish this helpful for you all.

The poor quality products are mostly design and made by China native small companies. These comanies have almost no quality control system. Lower the cost is their first aim. But China also provide high quality OEM products. The quality depend on the customers requirment and the factories you are cooperating with. Of course, the higher the quality, the higher the price.

Interesting thread.
As a distributor for Home Automation electronics, I can tell you that a large percentage of the electronics is manufactured in China. For the most part, the quality is really very good. The important thing, I think, is the company that does the QA and support of the products.
