Why can't I get the LED assembled ? (dangerous bug, no warning)

I am adding some led's like:  [https://lcsc\.com/product\-detail/Light\-Emitting\-Diodes\-LED\_0603\-Yellow\-light\_C72038\.html/?href=jlc\-SMT](https://lcsc.com/product-detail/Light-Emitting-Diodes-LED_0603-Yellow-light_C72038.html/?href=jlc-SMT) It is a basic part. Looks like: ![Screenshot from 2020-01-24 22-27-42.png](//image.easyeda.com/pullimage/WyS02Q8O9I0Wn7gm1fCHIGrtVdW4633hHFSAe7ij.png) I export BOM, they are there: ![Screenshot from 2020-01-24 22-35-56.png](//image.easyeda.com/pullimage/pUUk08ShrpuLa4OCrYxBd40IxqXIf4Q50SUNB1uL.png) I try to order PCB, and in the "select parts" step, they are completely omitted in the list ! -A dangerous bug, one could easily place and order and get very incomplete PCB's.

it seems this is a result of NOT having clicked update on the PCB after changing components. This should be handled automatically (cause a warning)

no, it was not that, once the LED's were updated and placed on PCB,  they went away again..

I'm having a similar issue. Goal: Using JLCPCB 'basic' smd parts have some led's and 74HC595D x2 (shift registers) assembled using the smd assembly service. The issue: My 74HC595D is not showing up in the "Select Parts" of the smd quote/order user flow. in the pictured the lower red box is where my two 74HC595D's should show up. :/ Note: 74HC595D are a basic part so should be 'pick and place'-able by the smd assembly service. ![Screenshot_1.jpg](//image.easyeda.com/pullimage/Si47GGqErZBgsTqJPzKuzAClfxpJEPss6VO4NUtb.jpeg) What I checked : \- See if the bom & PickAndPlace file included the my part 74HC595D\, yep looks good; \- rexported bom & pick and place & gerber file\. No luck\. :/ wierd - ![Screenshot_2.jpg](//image.easyeda.com/pullimage/mRUFHI0tCh9rGTtWU6WX7bG8m9k66EM4pRaYz3be.jpeg) - Pictured is the pick and place file ![Screenshot_3.jpg](//image.easyeda.com/pullimage/BhitNVIXRNUxFQVCY7Xmx1jZAU4S8zBpAMPKe7N8.jpeg) * pictured is the bom file ![Screenshot_4.jpg](//image.easyeda.com/pullimage/gYK9AfQdeYSQUAa1drLFlQxdxrA8Au6W9RHk62XF.jpeg) Any Suggestions? Comments?

@oranbusiness We don't have  “74HC5950” in our library stock .  Now we only  support components from our stock ([https://jlcpcb.com/parts](https://jlcpcb.com/parts))

@JLCPCBsupport, I think I know what has happened. I think it is a BoM parsing error. Let me explain... The part is not “74HC595**0**”: it is “74HC595**D, 118**” The customer's BoM shows that this part is LCSC stock number C5947 of which you show 81244 in stock: ![image.png](//image.easyeda.com/pullimage/gFB85L1bS7EiYjUFxOZ3sIB9ZoVGEtpHRcc2JrO5.png) However, what has happened is that in the BoM, the full part number field of “74HC595D, 118” has been parsed incorrectly by the BoM creation tool and it has been split into two fields: “74HC595D" and "118” and this has messed up all the following fields by pushing them one - and then further right where the same parsing error has occurred again; two - columns to the right. This has then also messed up the parsing of the **Designator** field contents of "U1, U2" by splitting that into two separate fields: "U1" and "U2" So the whole row in the BoM is broken because the column contents no longer represent the correct information fields: ![image.png](//image.easyeda.com/pullimage/Ch8Arzav3n3tN77rQoWZ0xSUT6Hgw0j4RIeiZ9Jg.png) See Bug Report: [https://easyeda.com/forum/topic/EasyEDA-BoM-parsing-error-also-breaks-the-JLCPCB-SMT-assembly-BoM-processing-086d33278e1040f0875d65d4cdc85454](https://easyeda.com/forum/topic/EasyEDA-BoM-parsing-error-also-breaks-the-JLCPCB-SMT-assembly-BoM-processing-086d33278e1040f0875d65d4cdc85454)

Really thanks for your feedback . Now bom formats of jlcpcb and easyeda are  incompatible. We need to contact  easyeda to handle this .
