Hoe kan ik een losse verbinding tussen component en printplaat voorkomen??

Het is een mooi uitziende broodplank, maar de aansluitingen zijn te los om een ​​goede verbinding te maken met alle componenten. so I couldn't actually use them for anything.

If your order has not been placed, I remind you to tell your supplier the pin diameters of the component that will be on this board.

Echter, your order is finished. But there is still a solution.

  • Use the components with an advisable pin diameter.
  • Vervolgens, keep other components with too thick pin diameters in stock, for the next order.
  • Don’t forget to tell the pin size to your supplier next time.

Wat anderen vragen

Zijn er problemen als ik verander? 0805 te 0402 opbouwmontage of kleiner?

Om de grootte van een PCB te verkleinen, Ik zal waarschijnlijk kleinere SM-componenten moeten gebruiken. Ik gebruik momenteel vooral 0805 passieven, en ik denk erover om er heen te gaan 0402 or smaller. Apart from power dissipation considerations, any pitfalls I should be aware of when making the transition?

Do you use SMT or THT for USB mini B connector?

This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn’t you use a through hole connector?

How can I connect my small PCB with sensor to the bigger PCB?

My small PCB is mounting a very sensitive fragile sensor on the top surface that has to be wire bonded to the PCB, so I am trying to design a smaller PCB that can be surface mounted to the bigger PCB. How can I get some kind of thin footprint for interconnecting the two PCB boards?
