content: Hello,I was just researching assembly for one of my projects so i went and searched "Headers" in the JLCSMT library and found though hole components.https://jlcpcb.com/parts/componentSearch?searchTxt=headerAnyone tried ordering a assembly with though hole components, do they actually solder them or are they just in the box so you can solder them yourself?Specificly i found C124386 which is a Pin Header 8 2 Straight 2.54mm header which really caught my attention.

content: At my job the thru hole connectors and other thru hole parts pass thru an wave soldering machine, or we solder them by hand if needed ?

content: I did not use it but juste made a pcb with come component and they charge a fee for those parts and a soldering fee per led so yes they install them by hand.

content: Exactly!I wrote to JLC yesterday just to be sure.They started hand soldering service a short time ago.That is just awesome!

content: Yes, but JLC SMT didn't give you access to that before. It is something all new they have added recently.

content: Yes and I’m using easyeda and those pet will not show up in easyeda I have to go to the website and use the part number to make sur it’s available!

content: This is all very new. I have yet to see a report from anyone who has used it. I have a lot of questions. Is there a TH equivalent of the CPL file? Are there conventions for the center of a TH part (Kicad uses pin 1 of connectors, is that it?). A number of parts do not have an obvious center given in their datasheets - like USB connectors (even SMT ones).When JLCPCB added the TH stuff, I asked about guidelines and they said they were working on them. Haven't seen anything yet.

content: I didn't yet run an actual job by them, but I uploaded and fitted a PCB including a USB connector. They charge a fixed setup fee plus a fee per solder joint. I assume that they assemble those parts by hand.

content: Quote from: thinkfat on February 17, 2021, 07:32:35 pmYes, by hand for the TH parts, I believe. Does that mean no additional information beyond BOM is needed? Just make sure there is a clearly visible part designator on the PCB and they will do the right thing? Maybe I will try a simple board with a couple of different TH parts to see how it goes.My point of confusion is how SMD connectors are done - by hand? I don't see a center point in any of the SMD USB connector datasheets that I looked at. How does one provide a correct CPL entry for PNP?

content: I added rj-45 jack using easyeda and it show in the 3d smd preview correctly so I guess if you use easyeda they will know where to place it! For smd usb connector I don’t. See why it would not be placed by the pick and place and reflow soldered?
