The electrostatic protection is important on PCBA board

During SMT processing, electrostatic discharge can cause damage or failure to electronic components. With the improvement of IC integration and the gradual reduction of components, the impact of electrostatic discharge becomes increasingly severe. According to statistics, static electricity accounts for 8% to 33% of the factors that lead to the failure of electronic products, and […]

The Importance of Impedance Control in PCB design (and how to avoid Signal Integrity problems)

What is Impedance Control and Signal Matching Impedance control is matching PCB trace dimensions and locations with the properties of the substrate material to make sure that the strength of a signal traveling along a trace is within a required range. The continual increase in device switching speeds is confronting engineers with signal integrity(SI) problems and eventually, most devices are going to have to deal with SI issues. So, Printed […]

The meaning of each layer of PCB board

PCB boards are usually composed of multiple layers stacked together, with each layer performing a different function. The following are common PCB layers and their meanings: Signal layer: The signal layer is one of the most important layers on the PCB board. It contains the signal transmission path between electronic components and realizes signal transmission […]

Incoming Inspection

1.Incoming Inspection Incoming inspection refers to the confirmation and verification of the quality of purchased raw materials, components, or products, that is, the quality is inspected through sampling when the supplier sends the raw materials or components, and the final judgment is made whether the batch of products is accepted or rejected. 2.Meaning IQC is […]

PCB-stackup-designguide | Fra materialevalg til stackup-design

Hvad er PCB-stackup? Under normale omstændigheder er det ikke nødvendigt at overveje PCB's lamineringsproblem, når man designer almindelige enkelt- eller dobbeltsidede kort. Normalt vælges et kobberbeklædt kort med en kobbertykkelse og en pladetykkelse, der opfylder designkravene, direkte til direkte behandling. Men når man designer et printkort med [...]

Hvordan sikrer man, at leveringen af PCBA-kort til kunden er intakt?

Når SMT patch proofing af SMT small batch patch processing factory er afsluttet, kræves der nogle opfølgende behandlingsprocedurer, såsom test, montering osv. Når alle de elektroniske behandlingslinks er afsluttet, leveres det til kunden. Det er relativt let at blive forstyrret af forskellige faktorer i forbindelse med levering og transport [...].

Rengøringsmetoder og krav til printkortet

Alle producenter af printkort skal overholde de rette rengøringsstandarder. Nu er udseendet af printkortets renhedskrav mere og mere strenge, uden at det påvirker kortets arbejde, vores DYC-fabrik har arbejdet hårdt for at levere et rent printkort til hver kunde。 1.Overhold IPC-5704 Al udvikling af medicinsk udstyr [...]
