[sdiy] Does anyone here use JLCPCB for SMD assembly ?

[Mike Bryant]

Well I just picked one at random and immediately hit the fundamental problem with European manufacturing.



"We constantly work at least two shifts, often 6 days a week."



Chinese companies work 24/7, so a product moves through the factory at a constant rate with no stops, except at the three annual holiday periods when all maintenance is performed.  You can see this from the times on my latest PCB as shown below.  The product flows through smoothly.



As it takes the same time to fly something from China to Heathrow as from anywhere in Europe, with a product that takes say 2 weeks to go through from order to delivery, you’ve got to add over a week extra at a European plant, which is time lost on a product schedule.



I remember having this discussion with a UK blank PCB manufacturer over 20 years ago.  They were reasonably priced for full production on a planned 4 week delivery and we ordered vast areas from them, but for prototype and pilot runs they added huge (>400%) markups to supply PCBs on 3-7 days.  I queried this and was told they did prototypes ‘out of hours’ so had to pay people overtime to do it.  So I ordered from China, far more difficult and unusual to do back then, and it arrived 10 days later.

Here's a short list I made for a friend from UK who complained their local service in that are is terrible:



At one time when I was selecting manufacturing parter, I wanted JM to be the one. They seem to be super quality, and not that far from my place.

Back then they said that 100 of something with around 50 components is absolutely something they would love to do. But this may have changed.

Strangely enough I do all assembly in-house, so can't really share any first hand experience with those.



There was an article some time ago in industry magazine here about EMS, where they included a few of the companies. There was a chart with about

70 companies showing who does what. It's in jpg so you have to type all the links and in Polish, so if anyone is brave enough to try, I can share it.
